NAME

Keyword::With - provide new syntax to use a 'given' statement without an experimental warning

VERSION

version 0.001

DESCRIPTION

Provide a construct almost identical to given (...) { } that evaluates an list expression in scalar context (assigning it to $_) then executing a block of code.

NAME

Keyword::With

SYNOPSIS

use Keyword::With; 

with (5*3) {
    print; 
}

or

with ( some_func() ) {
   print "matches\n" if grep { m/$_/ } qr/abc/, qr/def/;
   print "does not match\n"; 
}

ADVANTAGES

No experimental warning

DISADVANTAGES

Cannot use builtins that modify $_ with with blocks because they will clobber the $_ value set by with (...) { }. This was already a disadvantage of given blocks.
