Yes, but the O.P. was asking about a silly example. Specifically, when
defining a function that receives pointers how many levels of indirection
are allowed in the declaration. In practice 99.9% of the time a single
level of indirection is specified and 0.09% of the time two levels are
specified. Etcetera. For example, if
func wtf(i ********int) {
}
is supported, which has eight levels of indirection, why isn't 16? 32? 64?
Etcetera levels of indirection supported when defining a function. It's a
silly question that shows the O.P. doesn't understand how compilers work.
Let alone how people use languages like Go in real life.
