__ctfe is a runtime construct, not compile-time. It cannot be 
used with static if. More over, it's only available *inside* a 
function that is currently being executed in a compile-time 
context. It has no role outside of that.

What problem are you trying to solve here? I mean, what is the 
problem with whatever dependencies std.bitmanip:bitfields has 
that makes you only want to import it during compilation?
