This is a bug report for perl from perl-diddler@tlinx.org,
generated with the help of perlbug 1.39 running under perl 5.16.2.
-----------------------------------------------------------------
[Please describe your issue here]
I was attempting to clean up some code and tried to use
a foreign phoneme, or word or letter base, specifically,
"·" (U+00B7 MIDDLE DOT) in an identifier in perl, but
got a syntax error.
---sample program---
#!/usr/bin/perl -w
use 5.16.0;
use utf8;
my $·=1;
---end---
Everything I read on the internet describe the above
as being part of a word or identifier, and it has the
properties Diacritic, Extender, Grapheme Base, ID Continue
XID Continue.
As near as I can tell in looking at definitions for Grapheme
base, it seems it is something that would be part of a word
or identifier -- having a similar function to a letter.
It's not an operator, and it's not punctuation. So is it
an oversite that is causing it to be flagged as a warning?
Or what's up... Truth be known, I was
actually trying to define it with "use constant" (thus as a sub)
defined as "." (a single period or dot) so my joined strings
didn't look so tacky.
use constant host => Subsite .".". Site .":". port;
could be something like:
use constant host => subsite .·. Site .：. port;
if graphemes were able to be included...
It seemed like this could be an oversight, but if not, I'd like
to have it be an RFE for including such in varnames/sub names...
Tnx. Going back to find some other char to use instead...sigh.
Perl beautification -- a truely thankless task.
