Pirate update
Some people like to do crossword puzzles, lately I've been amusing myself by getting some new feature of Python implemented on Parrot.
Here are some recent successes:
print filter(lambda x: x<5, range(10)) == range(5)
args={'a':1,'b':2,'c':3}
def f(a,b,c): return (a,b,c)
def g(b,c,a): return (a,b,c)
for j in [f,g]: print j(1,2,3)
for j in [f,g]: print j(a=1,b=2,c=3)
for j in [f,g]: print j(*[1,2,3])
for j in [f,g]: print j(**args)
The most fun discovery I have come across so far is that Subs
(a.k.a. functions) are true objects, i.e., can have properties and
can be specialized by overriding the invoke
method. This has allowed me to implement features like
default argument defaults.
Major todos include reconciling Python and Parrot exceptions, and getting classes to work right.
