At this point in SV there is no special status for std so this should
be a conflict and work in the same manner as normal.  Hopefully a tool
would tell you about this and you could choose to use a package prefix
reference to resolve to what you want.

$unit is "kind of sort of" like a package, however its names are
found lexically, not via import.  So if there is a lexically closer
import, that wins.  Example:
    package p;
       int x;
    endpackage

    int x;

    module m;
       import p::*;
       int y = x;    // means p::x
    endmodule

This is exactly the same reason that one would use in the following:

    module m;
      int x;
      task t;
         import p::*;
         int y = x;    // means p::x
      endtask
    endmodule
