This could be made much more sophisticated. The file containing the blocks
could say whether or not there are shadow blocks. This would enable a
'turnkey' without shadows, thereby halving the blockfile size.
Further, the file containing the blocks could be compressed; as with gzip or
similar utilities. A set of words >gz gz> (or something) would handle
compressing and decompressing. So one might have a turnkey 'blockfile' which
actually is compressed; further obfuscating the code for the casual onlooker.
I've been toying with this idea for the included retroforth.f (reva.f).
