This is *really* interesting. I've had a number of occasions where
overloading would be nice! It's going to be fun playing with this
when I get some time.
A natural extension (to me, anyway) would be to modify the parser to
allow actual operators as method names - removing the need for the map.
As in:
method ||(a)
return this.stringValue() || string(a)
end
Did you by any chance look at this? Do you have a feel how hard this
would be to implement? Is anyone interested in doing so?
And of course, given that syntax, how hard could it be to add
procedures also?:
procedure ||(a,b)
returm string(a)||string(b)
end
