# C Style Comments

This adds support for comments with embedded spaces. It is useful
for quickly commenting out portions of lines or larger chunks of
code during debugging.

Specifically, this provides for C style /* ... */ comments. It
works by patching `interpret` to make it ignore tokens until the
token is `*/`.

{{
  :done?   '*/ s:eq? ;
  :revert  &interpret unhook ;
---reveal---
  :/* (-a) [ (a-) done? &revert if ] &interpret set-hook ; immediate
}}

:test /* hello world */
