Someone correct me if I'm wrong. 

Manifest constants grew out of the necesity of one of the winapi projects. 
There are lots of constants in the win32 api and they were taking lots of 
space in the resulting binary. Most projects opted to declare constants using 
enum because they got replaced by the value at compile time.

For a short period there was even a manifest keyword implemented in DMD but 
it got removed right before 1.0.
