Not really.

But I'd not use _boringly anyway since it seems counterintuitive that
_cis would not work.

Scheme has symbols and strings, and how to map LilyPond to either is
sometimes a tricky decision.  In contrast, Lua has only interned
strings, so the mapping becomes a no-brainer.  Sometimes not having a
choice can be helpful.
