That's not an error, but a different way of writing the version
number, a way that makes it compatible with the old versioning
system. v5.6.0 in the new system is the same as 5.006 in the old
system. If you want v5.6.0, use $^V, not $].
From the perldelta manpage:
Improved Perl version numbering system
Beginning with Perl version 5.6.0, the version number
convention has been changed to a "dotted integer" scheme
that is more commonly found in open source projects.
Maintenance versions of v5.6.0 will be released as v5.6.1,
v5.6.2 etc. The next development series following v5.6.0
will be numbered v5.7.x, beginning with v5.7.0, and the
next major production release following v5.6.0 will be
v5.8.0.
The v1.2.3 syntax is also now legal in Perl. See the
Support for strings represented as a vector of ordinals
entry elsewhere in this document for more on that.
To cope with the new versioning system's use of at least
three significant digits for each version component, the
method used for incrementing the subversion number has
also changed slightly. We assume that versions older than
v5.6.0 have been incrementing the subversion component in
multiples of 10. Versions after v5.6.0 will increment
them by 1. Thus, using the new notation, 5.005_03 is the
"same" as v5.5.30, and the first maintenance version
following v5.6.0 will be v5.6.1 (which should be read as
being equivalent to a floating point value of 5.006_001 in
the older format, stored in `$]').
Cajo.
