Ok, I can see your logic and agree that it's better to live with the

I get the following parsing error:

Error: Cannot access hash at '' with parameters (near $date3 string:-)
at /usr/local/share/perl/5.6.1/Petal/Hash/Var.pm line 101


You can try it yourself by modifying line 14 in t/data/basic.html and
uncommenting line 89 in t/02__default.t.
