F# identifiers alphabet

[Korporal]

I noticed that we can use greek unicode symbols in F# but not (say) APL symbols. I can write a function named ρ but cannot write a function named ⍋.

Is there a reason for this restriction on the alphabet? is it constrained by .Net and the CLR?

I'd imagine you can use ⍋

I'm actually open to changing the F# spec to allow APL symbols in identifiers if there's a good clean spec of what's allowed. There's a reasonable practical use-case for this after all (porting APL code to F#)

@dsyme - That's encouraging, OK I spent some time today putting a suggestion together, I'll leave this to stew for a while and see how it goes.

Thanks
