Raku port of Perl's Sub::Name module
use Sub::Name;
subname $name, $callable;
$callable = subname foo => { ... };
This module tries to mimic the behaviour of Perl's Sub::Name module as closely as possible in the Raku Programming Language.
This module has only one function, which is also exported by default:
subname NAME, CALLABLE
Assigns a new name to referenced Callable. If package specification is omitted in the name, then the current package is used. The return value is the Callable.
The name is only used for informative routines. You won't be able to actually invoke the Callable by the given name. To allow that, you need to do assign it to a &-sigilled variable yourself.
Note that for anonymous closures (Callables that reference lexicals declared outside the Callable itself) you can name each instance of the closure differently, which can be very useful for debugging.
