Delaney, Timothy C (Timothy):
> a. def foo (bar) [baz]:
> b. def foo (bar) as baz:
> c. def [baz] foo (bar):
Note that c. is like Quixote
> d. def baz foo (bar):
> e. def foo [baz] (bar):
> (1b) is the most visually pleasing, but the
> lack of syntax means that the decorator doesn't
> stand out as well as (a). However, it's simple
> to syntax-colour 'as', so that's close to a non-issue.
> (1a) seems to be the most understandable, and is
> quite visually pleasing - the decorator is obviously special,
> but feels more like it's an explanatory note.
You left out
f. def foo (bar) mod [baz]:
The current patch is not really using a list, it is
using magic characters "[" and "]". Given that, it
could as easily use magic characters "mod [" and "]"
Option 1.f. still has all the syntax-coloring advantages
of 1.a., but makes it more obvious that the "mod [baz]"
is truly an optional annotation.
("as" is the shortest suggestion for "mod", but
not the only one. Also suggested are many variations
on "transformed_by", "modified_by", "decorators",
"providing", "extended_by", etc.)
