Unclear from this discussion whether it was explicitly pointed out, but
one thing I'd like to see from the "keyword" functions is that they
*not* appear in the package's symbol table.
It's annoying enough that when you do this
package My::Class;
use Scalar::Util 'weaken';
...
Then `weaken` is visible as a method:
My::Class->weaken( ... )
$myobj->weaken( ... )
It would be great if code could enable keyword-shaped operators like
"trim(med)?" and so on without adding massively to their exposed "API"
shape.
Already I have begun experimenting with keyword-implemented list
utility functions under List::Keywords - and those have the property of
only being lexically visible and not visible as object/class methods:
$ perl -e \
'package My::Class { use List::Keywords 'all' } My::Class->all(1,2,3)'
Can't locate object method "all" via package "My::Class" at -e line 1.
It would be great if the same could be said of
$ perl -e \
'package My::Class { use keyword 'string::trimmed' } ...
