What exactly is this called? It's kind of futile to grep for "v" in the perldocs. Where is it explained?

The only explaination I've seen is actually in perlvar, under $^V.

So, "use version" feature will now use this new literal form. But the version check on use for module imports does not! The code in Exporter::Heavy looks for a string beginning with a digit.

So, how does one check for the presence of a new-style version literal? Could check for a small chr, which won't be a printable string until v32, but that seems crude.
