Fix selectindices for `nothing` return type #705

Closed rafaqz closed 2 months ago

rafaqz commented 2 months ago

This fixes selectindices for tuples so that non-error mode still returns nothing. It also performance optimises this.

Unfortunately a @gernerated function was needed as I could not get it to fold away with @assume_effects and the Revise bug keeps giving false positives.
