I would want a var

Answer 1

More specifically, from the Golang Specs:

Slices, maps and channels are reference types that do not require the extra indirection of an allocation with new.
The built-in function make takes a type T, which must be a slice, map or channel type, optionally followed by a type-specific list of expressions.
It returns a value of type T (not *T).
The memory is initialized as described in the section on initial values

However, regarding function calls, the parameters are passed by value (always).
Except the value of a map parameter is a pointer.
