Re: repost of alike 'missing a way to extract data'

[Alex fxmbsw7 Ratchev]

i also wanna say
no extraction method is no good for a coding language ( no extraction as is
only minus ( substraction ) is possible but no .. )
why dont you just enable backreferences \<number> of match
for ${var/ and //
and impent a regex variant, as you do by [[ =~ anyway
