There is a difference between not able to parse at all and wrong parsing :)
Former is in SYNOPSIS. See die "Unable to parse!" if $ua->unknown; part

Yes this is parsed as safari and leading to a wrong result.
I've added this as a todo item in the code repo.

Actually original_version() (see below) returns it
as this is Opera faking as Opera, you can rely on original version().
"/25.872" is part of the version string. I can cleanup that part
if it's Opera Mini though. I'll think about it.

Yes, lots of thing are not documented (and some can change too for that reason).

Most of the accessors are not documented.
This particular accessor can be used to differentiate fakers:

So, with version() you'll get the faked IE version. If you really want to know the Maxthon
version the the original value can be checked.

Indeed, Pod is not complete. But also note the module version number,
it's not that mature yet.
Thanks,
