Description

This works:

`to-boolean(3)`

This does not:

`to-boolean(to-boolean(3))`

Real-world example:

`case(to-boolean(feature-state('selected')), 'red', 'transparent')`

This is a showstopper for me.

If it's hard to make parsing with hyphens work, maybe a workaround would be supporting camel case:

`case(toBoolean(featureState('selected'), 'red', 'transparent')`

Research direction

No files, tests, or entry points are named. Reproduce the nested `to-boolean(to-boolean(3))` and `case(to-boolean(feature-state('selected')), ...)` examples, then trace the parser's handling of hyphenated function names; done means nested expressions parse successfully without requiring camelCase names.
