Have reviewed 16 year old code for a very well known company in the last week with this exact comment peppered throughout, alongside delightfully helpful comments like:
// do not delete or change this it just works
// TODO temporary fix added 12/09/11 to fix incident must be removed ASAP
// CAUTION this returns false here instead of true like it normally does, not sure why
// if true then matched to valid account not is true
The snaps on this are giving me major flashbacks, though I can’t put my finger on anything specific. My mum was a seamstress and I’m sure I remember finding and playing with something exactly like this in her room as a kid back in the 80s. Will reply here if it comes back to me :) the fact it’s adjustable to fixed intervals via the snaps seems too purposeful and practical, though - especially with the metal presumably giving rigidity to whatever it’s used for.
