I'm baffled.
If the condition we are trying to check for is when "x is not within a
range of 0-10 inclusive" then this is as readable as it gets:
not (0 <= x <= 10) (I)
That's pretty much a literal, word-for-word translation of the
requirement into code.
Sure, you can can apply De Morgans theorom to transform that into
(x < 0) or (x > 10) (II)
That's just as correct, but now the code is one step removed from the
requirement statement.
IMO, (I) is _more_ readable than (II)
