is there a shorter syntax or operator for
defined $functionpointer ? $functionpointer->($value) : $value
i would like to have sth like the //-Operator, so that I can shortly write
$functionpointer //->() $value
or anything in that direction
what I don’t want to do is write an extra method, overload operators or so
No, there is none. There are discussion, though, about introducing it: What operator should p5p use for safe dereferencing at PerlMonks.
