Would probably aid discoverability quite a bit if optionAt: was used consistently, and (at least the convenient-for-implementing-not-so-convenient-for-using option handling in) NBNativeCodeGen >> #doesNotUnderstand: removedâ¦ The finder is unable to point me to users of optStringOrNull even when I know the selector, and the defaultOptions method (which was the first place I found with a list of options) contains far from a complete set of the total available options, it seemsâ¦ Cheers, Henry

I remember an optCoerceNilToNull, but that seems to 1) Only apply to pointer types (which could mean having to use char *, not String, and thus need to do encoding/decoding manually) 2) Be scoped to entire call, not single parameter (may or may not be more than a philosophical objection) Might be worth a shot though?
