The compiler would permit "123" + "456" to be concatenated as "123456" but when the multiplication node is examined, it would throw a type mismatch exception...

I see what you want to do now. First, parse the expression without type info except at the leaves. Write a tree walker to traverse this AST top-down and insert...
