Since "static if" is now legal at module scope, it's now practically a 
superset of "version". So it shouldn't be very complicated to move some 
of the functionality across. (There's a problem with using 'static if' 
instead of 'version' : if there's an 'import' statement bracketed by a 
static if, potentially you have to compile the program to find out which 
files are included. Obviously 'build' can't cope with that).
