Well, I don't think there's an *exact* substitute for that maximally
efficient pattern (but I'm no regex guru), but this ought to work:
/^ --(v\w*): <( 'version'.substr(0, $1.chars) eq $1 )> $/
And you could always write a rule:
rule partial ($str) {
$str.substr(0,1) <partial $str.substr(1)>?
}
Then you could just write:
/^-- <partial 'version'> $/
