Chained Comparisons ?

[John M. Dlugosz]

I know how comparisons are chained in Perl 6.  There is a very short section on 
it in S03.

So, are the operators infix:{'<'} etc. written in the normal way to take two 
arguments?  Then the language transforms A op B op C into A op B AND B op C on 
an innate level.  Does that apply to any user-defined operator with those 
names?  If I want to make my own chained operator, perhaps the curvy &#8828;, 
&#8829;, etc. or make my operator &#8807; a synonym for >=, how would I tell 
the compiler that they belong to the same set of chained operators?

Or, are the operators written in a tricky way, to return an object that 
encapsulates the original right argument and the proper boolean result, and has 
forms to take this object as well?  IOW, no built-in support.
