ah, interresting.
i already noticed that python 2.3 supports things like:
union = a & b
isect = a | b
diff = a ^ b
so if there is a method for every operator then python maybe could be extended
to support all of those to the extend that pike does. (one of the prides
of pike is that all operations work on all types)

well, you have to make a choice in syntax somewhere.
other grouping characters are already taken for other uses.
the advantage of these is that they are very easely spotted in the code.
you just know that ({ 1,2 }), ([ "foo":"b", "bar":"a" ]) and (< "foo", "bar" >)
are values and not some other language constructs.

no. the code would simply not compile because of a parse error, and
you'd just slap your head once you see why.
in practice, this is never an issue.
(just like pythons indenting is not an issue, even though so many people
that never tried it love to complain about it)
