The other string literal method I personally use reasonably often is to
create lists of strings by using "a list of strings".split() instead of
['a', 'list', 'of', 'strings'] (while the character count isn't all that
different, I find the former is easier to both write and read without
all those quotes and commas). It's a trick I've seen plenty of other
people use as well.
So I would agree that method invocation on literals (particularly string
literals) is an already established language idiom.
Cheers,
Nick.
