Currently any kind of desctructured map ends up emiting a check if the destructured argument is a seq to support kw-args style turning it into a map.
The `(implements? ISeq gmap)` check is using a macro and ends up emitting something like this JS
Which when optimized still leaves
If we instead create a simple helper fn that does the conversion we could end up with
Given how often destructuring is used this could reduce a code size decently. Given that is not always uses the same variable names when checking this doesn't gzip-away so well otherwise too.
