Under Perl 5.6\, the variable $] contains the value 5.006 rather than the expected 5.6. $^V contains 5.6.0.

Before you jump in and tell me that $] is deprecated; it's not\, it's just old\, and it's more portable given that $^V isn't defined in pre-5.6 Perl. So\, if I'm going to do the test of "is this Perl less than Perl 5.6) I need to use $] to do it.

Unfortunately\, 5.006 _is_ lt 5.6!

Code to reproduce​:

  require 5.6.0;

  print "Running Perl version $]\n";   print "Running Perl version ";   printf ("%vd\n"\, $^V); # uninitialized var in 5.004 and 5.00503

  warn "No 'our' declarations!\n" if $^V lt v5.6;   warn "Cannot use our in version $]!\n" if $] \< 5.6;

Output

Running Perl version 5.006 Running Perl version 5.6.0 Cannot use our in version 5.006!

That is correct. The numeric version of perl5.6 is 5.006.

Before you jump in and tell me that $] is deprecated; it's not\, it's just old\, and it's more portable given that $^V isn't defined in pre-5.6 Perl. So\, if I'm going to do the test of "is this Perl less than Perl 5.6) I need to use $] to do it.

Code to reproduce​:

require 5.6.0;

That will not generate the intended behavior in older versions of Perl. (They will complain that the module 5.60 is not found.) Use require 5.006 instead.

print "Running Perl version $]\n"; print "Running Perl version "; printf ("%vd\n"\, $^V); # uninitialized var in 5.004 and 5.00503

warn "No 'our' declarations!\n" if $^V lt v5.6; warn "Cannot use our in version $]!\n" if $] \< 5.6;

That should be​:

warn "Cannot use our in version $]!\n" if $] \< 5.006;
