Hi
It might seem odd to use 'apply' as a decorator, but it can make sense.
I want to write:
# Top level in module.
tags = <complicated list>
where the list is most easily constructed using a function.
And so I write:
@apply
def tags():
value = []
# complicated code
return value
And now 'tags' has the result of running the complicated code.
Without using 'apply' as a decorator one alternative is
def tmp():
value = []
# complicated code
return value
tags = tmp()
del tmp
Like all uses of decorators, it is simply syntactic sugar. It allows
you to see, up front, what is going to happen. I think, once I get used
to it, I'll get to like it.
The way to read
@apply
def name():
# code
is that we are defining 'name' to be the return value of the effectively
anonymous function that follows.
