Incorrect Auto De-referencing of &net.TcpConn in Map Access

[M1ndo]

Describe the bug

Incorrect handling of pointers within maps, when attempting to access a map that contains nested maps, where the innermost map's values are pointers to net.TcpConn objects.

Reproduction Steps

Create a map with a string key and a value that is another map, where the inner map's values are reference to net.TcpConn objects (eg) con_list map[string]map[string]&net.TcpConn.
Attempt to access an element in the inner map.
Observe that the returned value is a pointer to the reference net.TcpConn object, not a reference.

Full source code: transport/transport.v https://0x0.st/Xr_o.v
main.v https://0x0.st/XrzL.v

Expected Behavior

Accessing an element in the inner map should return a reference to the net.TcpConn object (&net.TcpConn).

Current Behavior

A pointer to the net.TcpConn object is returned instead of a reference. (&&net.TcpConn)

Possible Solution

A possible workaround would be to create a mutable copy of reference.

for _, connection in unsafe {conx.con_list[id]} {
   mut actual_connection := unsafe {connection}
