My preference is to have names that are unique as a way of preventing confusion. If you call your method SaveAs, and your module invokes a method by the very same name from another module, then at maintenance time I have to be smart enough to know that the good old SaveAs from Win::OLE is not what the code is referring to. In other words, since another module already uses the term SaveAs, can't the method within your module have a slightly different name?

And on the note that it's nice to have unique terms for new pieces of software: I see that WordWriter is actually a commercial package written in Java for creating Word documents and also that Ken Tomiak uses perl2word as the name of a sample Word document maker (Win32::ole and MSWord). However, I don't see any hits by google for pl2word and so perhaps this could be the name for your module. Although the letter l looks a lot like the number 1....
