getKey? function takes an object and a
value, and returns the corresponding public key (or
nil), on top of a boolean flag recording whether
such a value was present:
makeIndex --> o Stack: 1 --> o["a"] o 1 getKey? Stack: t "a"
Note: Muq version -2.9.0
getKey? does not support
searching of objects.
getKey? function may also be used to search
vectors and stacks for a given value, returning the
corresponding key (offset). Vectors are searched starting
at offset zero, stacks are searched starting at the top.
This function does nothing that could not be done equally easily in muf, but it puts the inner loop down in C, hence may run a couple of orders of magnitude faster.
