That could have worked :) lambdas , lambda The first lambda language to go mainstream ? a new keyword "lambda language" https://en.wikipedia.org/wiki/Lambda_language https://en.wikipedia.org/wiki/Lambda_language#Lambda_calculus_and_programming_languages https://en.wikipedia.org/wiki/Lambda_language#Anonymous_functions https://en.wikipedia.org/wiki/Anonymous_function https://en.wikipedia.org/wiki/Anonymous_function#Closures https://en.wikipedia.org/wiki/Anonymous_function#Currying https://en.wikipedia.org/wiki/Anonymous_function#Perl Perl 5 supports anonymous functions, as follows: `(sub { print "I got called\n" })->(); # 1. fully anonymous, ca +lled as created my $squarer = sub { my $x = shift; $x * $x }; # 2. assigned to a varia +ble sub curry { my ($sub, @args) = @_; return sub { $sub->(@args, @_) }; # 3. as a return value o +f another function } # example of currying in Perl sub sum { my $tot = 0; $tot += $_ for @_; $tot } # returns the sum of +its arguments my $curried = curry \&sum, 5, 7, 9; print $curried->(1,2,3), "\n"; # prints 27 ( = 5 + 7 + 9 + 1 + 2 + +3 )` [download]	[reply] [d/l]
