The return value of the subroutine is inserted into the expanded string,
unless
-the return value is &%undef%&. In that case, the expansion fails in the same
-way as an explicit &"fail"& on a lookup item. The return value is a scalar.
+the return value is &%undef%&. In that case, the entire expansion is forced to
fail
+(see section &<<SECTforexpfai>>&). The return value is a scalar.
Whatever you return is evaluated in a scalar context. For example, if you
return the name of a Perl vector, the return value is the size of the vector,
not its contents.
