There are good reasons for many of those things. Vars begins with an upper-case V because vars is a Perl reserved word. All the other functions use lower-first casing, so better to make the one exception than change the entire module's syntax.

The prefixed minus is familiar to me from another language (I can't remember which, now) -- it's not an attempt to make them look like shell arguments, but rather a very common style; I suspect the author(s) of CGI.pm were used to using and seeing that style for named parameters. Because of this, when my functions accept named parameters, I use Params::Validate to normalize the keys, allowing but not requiring the prefixed minus.
