in thread Function name in a variable, can't recall the concept

\&$name works even under strict refs. No need to turn it off.

You need to return something (undef?) in the else case.

    Perfect, makes the code even simpler

    Good question actually. My tests didn't seem to need it...

    sub test { ... } ;
...
if ( my $s = get_sub_by_name( "", "test" ) ) {
    $s->() ;
} else {
    print "No\n" ;
}

      It wasn't a question. Your code relies on the result of an if statement with a false conditional being that false value, and it shouldn't.
