Shed Skin 0 0 20 and 0 0 21
development has been continuing at a steady pace, resulting in two new releases. I havent gotten around to cleaning up and improving tuple support, as of course I got bogged down into other details. the first release essentially combines many minor fixes:
Release Name: 0.0.20
-improvements to aug-assignments with subscripting (a[x, y] += 1 and such)
-fixed some problems with slice-assignments (a[1:-1] = [1,2])
-make integer division (/,//,divmod,floordiv) equal to CPython for negative/positive combinations of arguments
-make printing of floats closer to CPython
-move generic functions/methods to header file
-many small fixes (allow self as function argument, list.extend takes iterable, __delitem__ overloading, raw_input(), return from generator..)
-improved error checking for dynamic types
-optimize expr**2 and expr**3 using __power2 and __power3 functions
the next release is more interesting. first, a problem exhibited in a little program bearophile sent me (I wish there were two bearophiles :-)) gave me the insight that two things I was doing during type inference were more or less the same; this allowed me to generalize things and cut away about 100 lines. second, I added support for bisect, collections.deque and improved copy support. finally, there were some important dict optimizations (dict[..] += .. and dict.__getitem__ now only index once):
Release Name: 0.0.21
-important type inference fix/cleanup
-support for bisect, collections.deque and string.maketrans
-improved copy support
-support for try, else construction
-some optimizations (dict[..] += .., ".join(sorted(str))")
-several minor bug fixes
