Many languages have only functions, so to describe any action you have 
no choice but to use a verb in function names.

Pascal, xTalk, and others have both commands and functions, each with 
its own semantic role.

Every statement must have a command, and may also contain one or more 
function calls.

Since the command is the verb, it makes sense that a function would be a 
noun, a thing that the verb acts on.

When in doubt, imagine you're in a meeting with some major industry 
player and you want to show off the beautiful simplicity of LiveCode's 
"English-like" nature - do you really want do show this?:

   get getWindowList()

So much more elegant, so much more natural, so much more tTalk, to 
simply write:

   get WindowList()
