Hi Slava,
What does the warning 'Literal value expected' signify? I get a bunch of
these warnings in my code and I'm not sure how to remove them.
e.g.
( scratchpad ) USE: bstore.query.clauses
Loading P" bstore/query/clauses/clauses.factor"
:warnings - print 1 semantic warnings.
( scratchpad ) :warnings
While compiling elts-match?:
Word: elts-match?
Literal value expected
"delegate" f
Nesting: { elts-match? }
I've pasted the vocab causing this below for reference; all the words
and predicates infer ok. Is the warning because of macros or inlines
that I'm importing or is there something I should be doing differently?
Many thanks,
Phil
