No, it's not. ${(P)b} is "the value of the thing named by the value of
b" and the value of the parameter a is an ordinary array consisting of
all the values of the associative array.
What you want are name references, that is, "the thing named by the
value of b" (note the difference -- missing one "value of"). Zsh
doesn't have those yet, and when it does they probably won't be
implemented via parameter expansion flags.
Also consider:
b="a[$k]"
print ${(P)b}
