The most graceful way to invoke a Perl subroutine when its name is stored in a variable is to use the arrow operator (->
) to dereference the reference to the subroutine and then call it as a regular function. For example:
my $sub_name = 'my_subroutine';
my $sub_ref = \&{$sub_name};
# Invoke the subroutine using the arrow operator
$result = $sub_ref->(@args);
This method is more elegant than using the &
symbol to call the subroutine, as it avoids some ambiguities and potential issues with prototype checking.
