It's all very confusing. I recommend you don't go there ;-) If you really want to know, under 5.6, you could specify v-strings, which look like v1.3.5. Now those things actually translate internally to UTF-8 strings. This was basically a hack that allowed things like 10.2.100.160 to work, and be both an IP address and the binary level IP address perfect for low level sockets to work. But in the 5.8 development cycle people have realised this is a horrible thing to do, and is fundamentally broken regarding versioning modules - for example what if you had "require v5.7.2;" in a perl script? Under 5.7.2 it would work fine, but rather than telling you "This script requires version 5.7.2 of Perl" under 5.005, it would just croak with a syntax error. Bad, very bad. So v-strings are going, to be replaced perhaps with a v-string class in an aim to support backwards compatibility.
