Can I create a Python extension module in D (instead of C) | 1,150,093 | <p>I hear D is link-compatible with C. I'd like to use D to create an extension module for Python. Am I overlooking some reason why it's never going to work?</p>
| 14 | 2009-07-19T15:10:18Z | 1,315,336 | <p>Sounds easy and people here who say it's just up to the C API don't know how difficult it is to integrate the Boehm GC used by D within Python. PyD looks like a typical concept proof where people haven't realized the real world problems.</p>
