Look at the types of "reserved" and "symbol" (from

Thanks, I'd thought it was something to do with incompatible types.
I can now create a simpler problem:

but that's feels a bit contrived; or I could use 'reserved' twice.
Perhaps I'd express my confusion better if I ask: Why are 'reserved' and
'symbol' different types?

You may consider using reservedOp for ":", depending on how ":+" should be
