You don't really want a flattened intersection:
A word definition like this:
: foo ( x -- x ) [ 2^ ] [ bitor ] bi ;
Shouldn't match ``set-bit``:
: set-bit ( x n -- y ) 2^ bitor ; inline
You probably want something that does something like a deep-each, then for
each subsequence, collecting any subsequence that is a duplicate of all
possible subsequences of all quotations, or something ambitious like that.
In the lint vocabulary, the lint word looks at all callable's trying to
find any definition that includes it as a subsequence:
GENERIC: lint ( obj -- seq )
M: callable lint
[ lint-definitions-keys get-global ] dip [ subseq? ] curry
filter ;
M: object lint drop f ;
M: word lint
def>> [ callable? ] deep-filter [ lint ] map concat ;
