Better would be if match can be an expression, just like if! Then you can do:

for nucleotide in dna {
 rna.write_b(match nucleotide {`A`{`U`}`T`{`A`}`C`{`G`}`G`{`C`}else{`?`}})
}

[Edit] Never mind! This already works.

the one above was only used for illustration

this RFC was rejected and just remains for discussion, comparisons with languages that have this feature and maybe, better proposals
