I'm just updating the Perl language definition to support the new
keywords and operators in 5.10. I notice that keyword.control.perl
includes 'switch' and 'case' (which aren't Perl keywords; it's given/
when in 5.10) and also 'select' which is a function rather than a
Is there a compelling reason not to remove switch, case and move
select to the functions list?
Also, because I'm a TM language definition newbie, does anyone have
any tips about how to handle the // (defined or) operator? In some
contexts // is an empty regex; in others it's an operator
my @x = split //, $line; # regex, common idiom to chop into chars
my $x = $y // $z; # operator, equiv: my $x = defined $y ? $y : $z
