Prelude is not imported in a module called Prelude

I expect this to work..

[nix-shell:~/ghc-zubin]$ cat Prelude.hs 
module Prelude where

foo = True

[nix-shell:~/ghc-zubin]$ ghc Prelude.hs 
[1 of 1] Compiling Prelude          ( Prelude.hs, Prelude.o )

Prelude.hs:3:7: error: Data constructor not in scope: True
  |
3 | foo = True
  |       ^^^^

But if I call my module Prelude then the implicit Prelude import is suppressed (despite the fact it comes from a different package).
