Use :: instead of ->
if (my $numeral = Scalar::Util::looks_like_number($user_radius)) {

Scalar::Util does not have an object-oriented interface.

Similarly, you can also import the sub:

use Scalar::Util qw(looks_like_number); ... if (my $numeral = looks_like_number($user_radius)) {

[ambrus]: (It might be easier to use the callback scalar as a guard, as in $c and &$c(); $c = ();)
[Corion]: ambrus: Hurr - yes, that might happen, as Prima will queue lots of stuff (Well, Windows will)
[Corion]: But I'm really amazed that it just took this little code (plus the idle handler I have in mind and something else dk suggested)
[Corion]: ambrus: I wrote the handler so that it stops the timer if it's supposed to be a one-shot
[Discipulus]: are you using Prima Corion? good morning Corion and ambrus, btw
