[Python-ideas] New str whitespace cleaning method?

[Joao S. O. Bueno]

Come on - this is Python, and we are talking about entering a string in code -
One doe snto want to do a "from myutils.stringutils import dedenter"
just to be able
to use long strings in code. - in other languages it might be normal to
go to arbtirary leenghts of boiler plate code to do trivial stuff.

But ..seeing the attention here, I guess I am indeed one of the 2 programmers
in the World who needs long strings with no white-space from indentation
in code and consider it should be part of the syntax, not a
possibility on the stdlib,
so..whatever.  :-/
