You can copy the address of a routine into a vector, if that vector type
is at least as "wide" as the type of the routine. More specifically,
 the vector must take _exactly_ the same inputs as the routine
 the vector must make _exactly_ the same outputs as the routine
+ the vector must take _at least_ the inputs that the routine takes
+ the vector must produce _at least_ the outputs that the routine produces
 the vector must trash _at least_ what the routine trashes
If the vector and the routine have the very same signature, that's not an error.
