Features:

• Function overloading

• Switch statement

• Runtime module creation

• Tail recursion removal

• Python 2 function annotations

• Python 2 safe tuple unpacking

• Assignment if condition is true

Examples:

Function overloading:

@overload.argc(1)
def f(a): print 'Function 1 called'
@overload.argc(2)
def f(a, b): print 'Function 2 called'

f(1)
f(1, 2)

Switch statement:

with switch(1):
    if case(0): print 'Awkward...'; case.quit() # case.quit() is the same as break
    if case(2): print '???'
    if case(1): print 'Phew! It works!'
    if case.default(): print 'Ummmm...'

Function annotations:

@fannotate('Return annotation', a=1, b=2)
def x(a, b):
    return 0

Assign if condition is true:

compare_and_swap('my_var', None, 2) # set my_var to 2 if it equals None
