Can you explain what you meant by currying here? I know what
the word "curry" means, but i am having a hard time seeing how
it applies to your example.
It's currying in the sense that instead of one function
which takes all the args at once, you have a function
that takes some of them (all except the thunk) and
returns another one that takes the rest (the thunk).
Could you make up an example that uses more arguments?
def with_file(filename, mode):
def func(block):
f = open(filename, mode)
try:
block(f)
finally:
f.close()
return func
Usage example:
with_file("foo.txt", "w") as f:
f.write("My hovercraft is full of parrots.")
Does that help?
