Subject: Re: [PHP-DEV] Intervals representation with brackets
From: 0xcafefeed@gmail.com (mm w)

Hello,

Even if you are introducing a new syntax, your approach is wrong to
get intersection and interval, I was not talkative
but the samples I gave you expose several cases

// This isn't bad, but it's not really what i want, and... what I wrote! ;-)

so I guess you don't even understand what your are doing ? playing
with range, you may read the documentation about those objects into
the Apple Foundation those are following the same model, dealing with
list of ranges.

anyway what you exposed was really unclear, try to be more didactic,
we don't have crystal balls, and somehow Ijust trolled you like you
did, so please we are people we need a context.

Best,
