In the test suite, could we perhaps aim for some
consistency on the use of hyphens versus underscores,
or at least articulate when one is used versus the other?
For example, assign-is-not-binding.t versus hex_chars.t
in the above.
Personally I vastly prefer hyphens to underscores,
Same here. Since the directly names already match m/^S\d\d-/ I'll
assume
that will be our standard.
but I
suspect people have good reasons for preferring underscores.
One reason (probably not a good one) is to use the same
convention as programming language variable names (which is
typically more of a CamelCase versus not_Camel_case issue).
With the small distinction that there are case insensitive, case
preserving and case sensitive file systems, whereas identifiers are
always case sensitive.
My experience is that it's hard to get case right on the former two
types of systems because you don't have real testing. That's why I'm in
favor of all lower case file names.
So would a user-supplied Perl 6 syntax-morphing module to allow
use of embedded-hyphens in variable names (and other names, such
as labels and subs) to Perl 6 (with minimally-sane adjustments
needed to make hyphen-related operator parsing unambiguous) be
reasonably feasible? Or does this open a messy Pandora's box of
cascading language-redesign kludges?
I think it could cause confusion, but it should be so easy to do that
you'll just be able to try it out. Just allow '-' in the mid of an
identifier, and longest token matching takes care of the rest. Since
whitespaces terminate LTM, they automatically disambiguate operators.
