Hi Doug,

I noticed that below mentioned if-condition was already present in
Nevilles' original version. I don't see a point in highlighting textual
operators but not highlight the symbolic variants. - Or what do you
think?

(There may be a point concerning all the Unicode variants we saw in
that version - these specific variants are unsupported by the Genie -
so they could be conditionally activated [in future] if/where possible.
But unless there's actual support from some compiler/interpreter I'd
remove the Unicode versions. - And then the conditional appears to
be unnecessary.)

Could we just remove the if-condition for the standard operators to
obtain them highlighted in Algol 68 source code? - Please let me
know what you think.

Thanks!

Regards,
Janis

Betreff: AW: [vim/vim] runtime(algol68): Update syntax file, match symbolic 
identity relators (PR #20109)

Just noticed that I don't see operators highlighted in my environment.

Q: Where will the condition   exists("algol68_symbol_operators")   get set
or when will it become defined, so that the highlighting gets activated?
