When a call is disallowed due to a parameter rule, display a different message

[spaze]

Discussed in #154

I'd like to disallow different methods, with different messages, dependent upon the number of parameters used. For example, if I've got function:

function foo($bar = '', $xyz = ''){}

I'd like to display:

• if foo() is used anywhere, display Don't use foo
• if foo(*) is used anywhere, display Don't use foo with parameter $bar
• if foo(*,*) is used anywhere, display Don't use foo with parameters $bar and $xyz

Is this possible at all?

Maintainer note: I think a param-level message could be added that would override the main message when a call would be disallowed due to disallowed/missing param.
