Are you sure?  But how did the old framework find out if a
WITH_* / WITHOUT_* variable came from make.conf or from the
command line?

For example, say the make environment contains WITH_FOO=YES,
but the OPTIONS file contains WITHOUT_FOO=YES.  If the above
precedence is to be followed, then the framework needed to
find out whether the WITH_FOO setting came from make.conf or
from the command line.  I don't think there's an easy way to
do that.

Best regards

"Python tricks" is a tough one, cuz the language is so clean. E.g.,
C makes an art of confusing pointers with arrays and strings, which
leads to lotsa neat pointer tricks; APL mistakes everything for an
array, leading to neat one-liners; and Perl confuses everything
period, making each line a joyous adventure <wink>.
