Minor comment.. I personally find it harder to type < > than : because the < > keys are a lot closer to the shift key and causes more wrist strain.

Have you considered borrowing the :emoji: convention that slack/discord/github use? :space: :feed: etc..

Hello Yoav! In my opinion the match keyword is not needed. When the parser gets to an opening bracket that should start whatever methodology the match keyword is doing. As a heavy regex user, I understand that you want consistency with the capture keyword behaviour. But if we assume that the user is a programmer but does not know regex, it makes more sense to view {<space>;"batman";} as an array (delimited by curly brackets).

In fact, you might want to go a step further and consider using [] for match and {} for capture (thus eliminating the capture keyword as well). Using [] for match would be natural for Javascript programmers.

I feel like there should be a way to group a portion of the regex, by name, for extraction later. Otherwise I like it.

ie

    group $first_name { some of <letter> }
    1 of <space>
    group $last_name { some of <letter> }
