Opened File.d at random:

@trusted
@nogc
char[] read(const string filename) nothrow {
     import std.c.stdio : FILE, SEEK_END, SEEK_SET, fopen, fclose, 
fseek, ftell, fread;

     FILE* f = fopen(filename.ptr, READ_BINARY);
     scope(exit) fclose(f);

     fseek(f, 0, SEEK_END);
     immutable size_t fsize = ftell(f);
     fseek(f, 0, SEEK_SET);

     char[] str = m3.m3.make!(char[])(fsize);
     fread(str.ptr, fsize, 1, f);

     return str;
}

Then stopped right there. This is nowhere near production quality - 
there is no error checking whatsoever, does more operations than 
necessary, won't work on special files etc. etc. etc.

I applaud the intention but there is a lot more work to be done on this 
before it's in reviewable form.
