The 'use VERSION' syntax only became available in 5.6

I don't know when it was introduced, but it was before 5.6. For example, it's present in 5.4.5.
(Upd: It was introduced in 5.4.0. )

it uses the dotted-numeric form that older Perl's don't understand

Isn't the syntax deprecated or invalid in future versions too?

older versions of Perl won't even compile it to report a proper error about the perl version.

It seems to me that syntax error at -e line 1, near "use 5.6" has a pretty obvious meaning. That's a poor reason.
