During the development of the
Sub::Lexical module I have come across what I
guess could be best described as a limitation of the nature of the module. The
problem is that there is no slot in the lexical scratchpad for subroutines so
for example the following code dies
my sub foo;
__output__
"my sub" not yet implemented at - line 1.
And
my &foo is an outright syntax error. So the the lexical subs
cannot truly be lexical subs but merely scalar references to
CODErefs.
But this introduces the problem of namespace issues e.g
use Sub::Lexical;
my $foo = "a string";
# ack, $foo = sub {}; will run over previous $foo :-/
my sub foo {
print "I'm in foo()\n";
}
Currently the workaround is distinctly horrid and involves inserting a double
underscore around the variable name so
$foo becomes
$__foo__.
I'm possibly missing some blatently obvious idea or maybe this is an inherent
limitation of perl (and with good reason?).
Thanks
