[BUG] Still having issues getting macros to "fully" resolve

[matthew-dean]

Describe the bug
I finally came back to this. I'm still having an issue where not all the function calls will reduce / resolve no matter how much I try to pepper with macros.

Code to reproduce

import { build as $build } from 'xregexp';

// ... tokens and stuff

function $buildFragments(rawFragments: string[][]) {
  const fragments: Record<string, RegExp> = {};
  for (const fragment of rawFragments) {
    fragments[fragment[0]!] = $build!(fragment[1]!, fragments);
  };
  return fragments;
};

export const cssFragments = $buildFragments!(rawCssFragments);

Results in:

export const cssFragments = (() => {
    const fragments = {};
    for (const fragment of rawCssFragments) {
        fragments[fragment[0]] = $build(fragment[1], fragments);
    }
    ;
    return fragments;
})();

Expected behavior
I expected for everything to "resolve" to a single object in the compiled JS.
