Hello.

[Time for a new episode in our "Ripping CM" series.]

How about creating "Commons Geometry"?

The rationale is comprised of the usual suspects:
* Smaller and more focused component, hence:
  - Consistent development and maintenance.
  - Consistent release schedule, not encumbered by
    changes (and endless discussions) in _totally_
    unrelated code.
  - Potential for attracting contributors not
    interested in maintaining the (growing) backlog
    of CM.
* Self-contained: 96.3% of the "o.a.c.math4.geometry"
  package have no dependency except:
  - 4 classes now in "Commons Numbers".
  - 2 methods and 1 constant in "MathUtils".
  - CM exceptions. [Creating alternatives for those
    will probably be the most time-consuming part of
    the porting work.]

Moreover, none of the code in the "o.a.c.math4.geometry"
package is used by another package of CM.

A new component would give the "geometry" codes a much
better chance of being (confidently[1]) released, since
CM is "stuck" for the foreseeable future.[2]

WDYT?

I want to see the initial release of Commons Numbers before breaking
more components out of CM.

I'm among those who most want to see that release rather sooner
than later.  [IIRC, I posted regularly to inquire about the status
of the pending issues.  Is there more *I* can do at this point?]

I've no problem with serializing the "CM ripping[1]" project.

However, I wish to know what people think of the purely technical,
code-oriented, arguments which I've put forward above.

My suggestion would be to have a "beta" release of the new component
in order to let a community of expert/interested users voice its
opinion on the expected API.  [I think there is a lot of good and
broadly useful code in the "geometry" package (otherwise I wouldn't
ask for a new component) but I also suspect that the API can be
improved.]

Regards,
Gilles

[1] For its own good, and ours. ;-)

[1] There seems to be only one issue reported in JIRA
   that pertains to "geometry".
[2] 54 issues yet to be fixed before the 4.0 release;
   which, at the current rate, would lead to after 2025
   (a very rough guess, I admit).
