Do we need to do this before launch?

On thursday we should try to craft an example of where this might matter.

We noticed that if there is only a single function parameter (and it is having its type enforced), we are adding a redundant OP_DUP and OP_DROP. See this example:

                                           /* contract ParameterCheck() {                   */
                                           /*     function spend(                           */
                                           /*         bytes8 tag,                           */
                                           /*     ) {                                       */
OP_DUP OP_SIZE OP_8 OP_EQUALVERIFY OP_DROP /*         >>> parameter type check (bytes8 tag) */
OP_SIZE OP_NIP OP_8 OP_NUMEQUAL            /*         require(tag.length == 8);             */
                                           /*     }                                         */
                                           /* }                                             */

We either fix it with a special case, or we can choose to use OP_ROLL instead of OP_PICK, which reorders the parameters on the stack.

compiler docs are still missing the 2nd flag option

Compiler Options

interface CompilerOptions {
  enforceFunctionParameterTypes?: boolean;
}

and similarly in the release notes only has

🛠 Add compiler option to cashc (programmatic and CLI compilation) to allow for opting out of function parameter type enforcement.
