saves at least 6 gas. "less or equal" does not exist in the evm as a separate opcode, so to get the same effect, the compiler:

  • does a >, and does a ! on the result.
  • does a <, then a ==, then || both.

both variants need some stack manipulation, and take extra ops. but, you can just to a < check of the immediately larger value.
