So between
- function
- keyword
- function with named args
?
for me it depends on the complexity being expressed.
any time you transform something from one thing to another, you need a function.
I dislike the perl syntax like:
foo = sort keys %hash
and I dislike the Python
foo = hash.keys.sort
instead, function calls are much clearer about what's affected and where the
different functions start and end
foo = sort(keys(hash))
but for something that is a test, and can only give a true/false result (i.e.
something that you will do "if <something> then"), and it only involves two
items (one of which is always a variable), then I think good keywords work well.
a == b
a startswith b
a contains b
if it cannot be expressed with one variable and one other item (which can be a
variable or function return value), then it must be a function
If we did not already have contains and startswith, I could see avoiding this
entirely, but since we have these, I think continuing to use this approach for
other tests makes sense.
