The specification of Mininess in the Scalaness User Documentation says that the negative sign when applied to an integer literal is part of the literal. That is '-128' is a single token and not the '-' token followed by the '128' token. This is important because otherwise -128 will have type int16_t rather than int8_t as it should. In particular '128' must have type int16_t since 128 is too large to represent with int8_t. With the '-' sign as part of the literal token the compiler can see that '-128' is a legal int8_t value and assign it an appropriate type.
