No. It wouldn't be safe...(No matter what).

] | I do not agree to the formula "after certain number of words".
Note that the first target line has 4 words, whereas remaining 2 have
5 words each.
Actually you need to replace each comma and following sequence of
spaces (if any) with a comma and `\n`.
So the intuitive way to do it is:
```
$x =~ s/,\s*/,\n/g;

196 | I have been working on dynamic programming for some time. The canonical way to evaluate a dynamic programming recursion is by creating a table of all necessary values and filling it row by row.

* There are several natural dynamic programming algorithms whose tables require three or even more dimensions. For example: Find t... |

```
list([0.0,0.0]/sum([0.0,0.0]))

The loop generates all sort of other number vectors but it also generates `[nan,nan]`, and to avoid it I tried to put in a conditional to prevent it like the one below, but it doesn't return true.
