Luametatex evolves out of traditional tex so we have/keep some and
although i grew up in the 'anti goto' times (pascal) there are plenty
cases where i see no problem. Occasionaly I clean up such bits (when it
makes sense). And I'm not going to enter coding practice discussions.
Forget about refactoring ... there has already be done a lot of that and
we want to stay sort of close to the original (also due to
doicumentation). I know the code quite wel now and refactoring is for me
counter productive. These are projects running for decades and engines
need to be stable so changes come slow.
You can compare the luanmetatex source to luatex and pdftex to see how
we proiceed.
