You're mixing globbing with parameter substitution. Due to order of
operations (parameters before globs -- otherwise $SD/autoload/* would
not work) you can't do this via substitution.
Fortunately there are a lot of things you can do with globbing that
mimic parameter substitution, and :t happens to be one of them; you
can use it as a glob qualifier:
FUNCS=( $SD/autoload/*(:t) )
