In elder days before the fall of mighty kings in Gondolin the ancient scribes would also invert the order of assignment operators, writing
a =+ b
to mean what we now render as
a += b
. Digraphic operators have a nasty way of mixing up with monographic ones when whitespace doesn’t matter but order does: consider
a =- b
,
a = -b
, vs
a -= b
. Here of old be dragons, but none so great as before after Eärendil slew Ancalagon the Black and broke Thangoradrim beneath his fall. I was there when we thought evil vanquished forever, but ever it returns from the darkest of codes to trouble us anew. —
