I had need for a new #perl operator today, like:

$val //~ s/$prefix//;

that would be equivalent to:

$val =~ s/$prefix// if defined $val;

is it too late to get this for v5.42 ?

@Pyrrhlin @Perl cannot do that since // (~s///) would need to be deprecated first.
there are proposals for a more generic =~:u though
