"A noun modified by a number is never pluralized; that is to say, it is
invariably singular"
In the old grammar, DetQuant would always make the Det into numeral, and
so Sg was always chosen in DetCN.
The -path flags in the RGL modules compiled during 'cabal build' now refer
directly to the needed source directories. References 'alltenses' and 'present'
(and the nonexistent directory 'mathematical') have been removed.
This allows the files to be compiled in any order (e.g. in parallel). In
addition, you can do things like
gf -retain lib/src/api/TrySwe.gf
without compiling/installing any other RGL modules first, and without
setting any other path flags or environment variables.
