I write the names of arrays with a trailing "s", because seeing something like @function really throws me off. It looks like there is some sort of mismatch between the name of the variable and its plurality. To me, the "s" isn't redundant... it confirms at a glance that there are (possibly) multiple elements in the variable.

Of course, sometimes even a scalar variable can hold a reference to multiple elements (as an array reference, for example). In this case, there is no "@" to indicate plurality, so the "s" is necessary (in my mind, anyway). So, in my coding style,

• $function contains a single element
• $functions is probably a reference to an array containing multiple elements
• @function is a type mismatch in my brain, so I don't use it
• @functions is an array of multiple elements

That's not to say that either style is necessarily better. Mine just fits my brain better. I'm curious to see what other people think, as well.
