Just to clarify: I'm the original developer of Mono.GetOptions, and still
the main one.

Yeah, we have a blend of styles to accomodate, making gnuish as windowish
command lines possible. So we have compromises.
>For example, to provide Windows-style syntax, I need to handle
Currently you can use the non-optimal comma-pairing
also accepted in the /a name,value and /a=name,value
The problem is that Mono.GetOptions would not help a lot in that case. You
would need to now that sequential values are to be treated in pairs... We
will try to remedy it....

You can restrict a bit parsing, by choosing to not support gnu-style (there
is a flag enum that governs it), but yes some cases aren't so well treated,
because of the compromises (the worst of them is having to support both
styles in the same command line)

Yes, the idea I have just now is to associate parsing name-value pairs,
using the syntax you presented, only for types that implement IDictionary,
so there'd be a natural semantical match.

I came up with Mono.GetOptions long ago, because I needed it in mbas, and
since then some people has enjoyed using it inside mono utilities and
elsewhere. But Miguel told me today, that we need to discuss it better, to
make it a better tool to more developers.
I'm addicted to it, just can't do imperative parsing of options anymore, but
I want it to be as usefull as possible, so ...
... suggestions and patches are welcome.
