Yes. If so, I find the proposed symbol ugly. `=3D>' is already a semantically loaded indicator. I'm sorry, i don't understand what you mean. Outside of documentation and the mini-language Calc accepts, i don't see that symbol in use. Likewise, the individual tokens of `=3D>' are too visually similiar to `=3D' and `>'. I would prefer either `#=3D>' or `#->' which might help to convey the implicit function call involved. The hash is problematic, but really, any short symbol is fine with me. (I chose =E2=80=98=3D>=E2=80=99 out of familiarity w/ Scheme= .) Another idea is =E2=80=98:=3D>=E2=80=99 or even =E2=80=98::=E2=80=99, both = of which font lock nicely out of the box, for some extra visual distinction.
