Negation and strict processing are confusing

[ilsd]

The negation of switches (and other types) is confusing if argv is strictly parsed.

Switch('--rawdump')->default(1),

and on the command-line: --no-rawdump results in $opt->get_rawdump to be still 1. (--no---rawdump would work but is a bit bizarre imho.)

Workaround

Switch('--rawdump|rawdump')->default(1),

Than the negation switch --no-rawdump works as expected.

TODO

Should be documented at least or throw an error for the not working negation switch --no-rawdump.

Just my 2 cents to an otherwise great module.
