> Test suggestion: function containing all skipped opcodes, check that it's parsed to single `end`. Added.

> Do we need this? Yes. We need the `is_even()` implementation: https://github.com/wasmx/fizzy/pull/503/files#diff-0a1ee17a5a632aafe4ae0b789cb7d1b7R9

> @chfast maybe this with #602 would be measurable saving? It removes the passing of `func_type`. Yes. This was main goal.

> I'd merge #554 first / instead of this. This is the only effective change in #554. Rest is done by the compiler optimization.

> The reason I like #554 because that makes it apparent those are two different code paths and we should optimise separately. We can wait for the `std::function` work first...
