re: Nice grammar you got there. So... regular. Would be a shame if something... const HappenedToIt = input => { const re = /\d+|\)\]\[\(|\]\[/...
 

Point Guru wasn't so bonkers after all ;)

Perhaps a more interesting input would have been warranted

 

At least for paired tokens, I probably would have used a pushdown automata.

I only looked at the separators, not the paired wrappers.
Furthermore I didn't rely on the knowledge that the points are 2-dimensional.

You could say I have a stack of stacks of stacks :v

Points could just be space separated, the sepBy() combinator would address that restriction
