Only if it isn't byte compiled, which isn't recommended. cc-langs is
not even loaded when everything is byte compiled.

I still don't understand this aversion to the CL functions. I find it
absurd that there is an old and well established set of basic tools
that can't be used in many situations.

The only argument for that position I've heard is that the CL package
isn't namespace clean with some package prefix. That argument is weak
since it can't conceivably become a practical problem - the functions
are so old and well established that they are comparable to the
built-in functions. Anyone who would define a mapcan with any other
function than the one in CL would be both very silly and break the
namespace rules.
