I can't recover the original email so I'm not sure what was suggested, but
if the suggestion is to make define-abbrev signal an error if the abbrev
uses chars that are not word constituents, this will be problematic because
the criterion depends on the syntax-table in use and that one may not be the
same during define-abbrev as during expand-abbrev (some code in Emacs even
uses pre-abbrev-expand-hook to change the syntax-table used during
expand-abbrev independently from the syntax-table used otherwise in the
buffer).
