OK.  But you mean emacs is not seeing _ as operator, if I understand correctly.

GNU smalltalk supports _ as operator, and it works fine.

Except when you switch to a font that uses a "legacy" encoding,
where _ is displayed as a left arrow.  In that case, those variables,
with underscores in them, look weird.

They look weird because they contain left arrows.

My understanding is also that the GNU smalltalk manual also warns against
using _ in variable names as it may lead to portability problems.
