Are the nops because of the simplify-locals pass? Would we expect to get more than one?
I'm completely okay with leaving this as-is until we have a need a for loop here, because this is simpler / easier to read.

Yes, that pass will replace the initial set with a single nop. There won't be anything more here since there's just one constant in the whole function.

first = block->list[1];
}
// look into a return value
if (auto* ret = first->dynCast<Return>()) {
first = ret->value;
}
}
if (first) {
addrConst = first->dynCast<Const>();

I thought << curr printed the function body. Is that << *curr or does that not actually exist?
The thought being that printing the unexpected code inline with the error would be the information a user would really want, vs. the name which lets one look up the code later via wasm-dis.

Hmm, not sure what *curr does for a function. For an AST node, that would print in out. Here it was just printing the pointer until this PR, and now it prints the name (which seems sufficient for debugging to me at least ;)
