That's not an integer literal... that's a runtime value of ubyte
plus an integer literal.
Since the ubyte is the result of a runtime function, the compiler
doesn't know what it will be and thinks it could be anything from
0 to 255, inclusive.
240 + 16 = 256 = too big to fit in a ubyte, to it requires a cast.
ubyte code = 16; // this would work
ubyte code = 239 + 16; // this too
but yours won't because to!ubyte(spec, 6) might just be > 240.
