The specification currently uses ++ for concatenation, which seems
clearer to me unless there's a pressing desire to use that operator
for something else.
As used there it also appears to be a coercing concatenation ("Pi = "
++ pi), rather than String ++ String. I have implemented it so far
with automatic coercion by asString from any object.
