In C, a struct can have another struct as one of it's members. While this isn't exactly the same as what you're asking, you could end up either with a situation where one struct contains another, or one struct contains two structs, both of which hold parts of the info that you wanted.

For python you can try using [processing module][1].

FYI, in this particular case, the reason the `IBOutlet` even exists is simply so that Interface Builder can parse the source file and glean bits of understanding from it. It's a clue (well, a bit stronger than a clue) that the variable preceded by `IBOutlet` should show up as an Outlet in Interface Builder when design... |
Mike Rettig created a .NET library called [Retlang](http://code.google.com/p/retlang/) and a Java port called Jetlang that is inspired by Erlang's concurrency model. |
Using non-greedy quantifiers here is probably the best solution, also because it is more efficient than the greedy alternative: Greedy matches generally go as far as they can (here, until the end of the text!) and then trace back character after character to try and match the part coming afterwards.

This will work. It's messy because in BAT files you can't use set var=\`cmd\` like you can in unix.
The fact that echo doesn't understand quotes is also messy, and could lead to trouble if `Some Pattern` contains shell meta characters.

How do I make bash reverse-search work in Terminal.app without it displaying garbled output? |

Using Terminal.app on OS X 10.5, often you see the commands get garbled when you do a reverse-search with Bash. Is there some kind of termcap or perhaps a bash shopt command that can fix this? It is very annoying.
Steps to reproduce: Open Terminal.app, reverse-search to a longish command. Hit <ctrl>-E once you... |
I wouldn't recommend just making the switch on an existing project.

If you want a pen and papper kind of exercizes I'd recommend more designing than coding.

To use the least amount of space you should use a CHAR field constrained to 'Y' or 'N'. Oracle doesn't support BOOLEAN, BIT, or TINYINT data types, so CHAR's one byte is as small as you can get. |
You probably have to go with some out of band signaling: have the producer of "file.ext" write a dummy "file.ext.end". |
Doing your own BigNum library is complicated, so i'd say like jjnguy. Use whatever your language offers as libraries.

You mean change the text file before it's committed? You can (I'm not sure how), but it's generally not a good idea, as it doesn't tell the client about the change, so the local copies become void on a commit.

Given your mention of "C#'s reflection power", I am unsure whether you're looking for an interactive C# console for small code snippets of your own (à la Ruby's `irb`), or a means of interacting with an existing, compiled application currently running as a process.

Seems like dealing with licensing issues would be nightmarish for the host. |
As an interesting side note, WPF's binding handles marshaling automatically so you can bind the UI to object properties that are modified on background threads without having to do anything special. This has proven to be a great timesaver for me.

Well, `".*"` is a greedy selector. You make it non-greedy by using `".*?"` When using the latter construct, the regex engine will, at every step it matches text into the `"."` attempt to match whatever make come after the `".*?"`. This means that if for instance nothing comes after the `".*?"`, then it matches nothing.... |
