No - perl 5.6.0 has internal version number 5.006 (and 5.7.0 will be 5.007).
And perl's "require" statement indeed expects this internal version number.
So using 'require 5.6;' to request perl 5.6.0 or better may seem correct, but
actually requires perl 5.600 (5.600.0 I suppose) which won't be released for
a long, long time.
