[E-Lang] Operators #8: Non Python expansions

These are the remaining expansions for which I couldn't find a Python 
analogy.  If I missed a section of the manual, please lemme know so I can 
make more compatible choices.

    !x          ->  x op__not()
    x..y        ->  x op__thru(y)
    x..!y       ->  x op__till(y)
    <foo:body>  ->  foo__uriGetter op__getitem("body")
    <foo: expr> ->  foo__uriGetter op__getitem(expr)
 
When x and y are both positions in type-as-coordinate-space T, then

    x..y   means the same thing as   T >= x & T <= y
    x..!y  means the same thing as   T >= x & T < y

Among the core datatypes, "!x" is only expected to be defined on booleans.  
To complement a region, use "~x".


        Cheers,
