First, thank you for all opnion. Each one was considered.
I think the better question would be:
I have to develop a project that involves compilers, and being a fan of
Python, I thought about making a compiler for it (most basic idea
involving
Pythin and compilers). But I saw that I can use what I learned from
compilers not only to create a compiler. What is the area of
developing the
Python interpreter that I could build my project, and please give me
interesting ideas for the project.
I don't think the question is necessarily off-topic.
I can propose two projects, related to Python core:
- 2to3 pattern compiler: 2to3 currently uses an interpreter for pattern
matching. It does "compile" the patterns into some intermediate form,
however, that is actually interpreted with an interpreter written in
Python (actually, it is self-interpreted). It might be interesting to
compile the pattern into actual Python code, with the hope of it
executing faster than it does now (and yes, I proposed a similar, but
different GSoC topic also; the two approaches are orthogonal,
though).
- IDLE code completion. Currently, IDLE has some form of code
completion, which is fairly limited. It might be useful to produce a
better code completion library, one that works more statically and
less based on introspection. In particular, optimistic type inference
might help (optimistic in the sense "if foo has a method .isalpha, it
probably is a string). In code completion, exact type inference isn't
necessary; giving a superset (i.e. a union type) might still be
helpful.
This would be very useful to many Python IDE projects. Getting it
right is one thing, getting it fast enough to be useful is another
(i.e. it is a difficult problem) - but yes, could be both interesting
and useful.
A good basis for a project like would be PySmell (by Orestis Markou),
which intended to provide this but was never completed:
http://code.google.com/p/pysmell/
It would make a great gsoc project as well.

In addition, to-python compilers may also be interesting in various HTML
templating languages, e.g. Django templating, Zope page templates, and
the like (although some of them already have compilers of some form on
their own).
HTH,
Martin
