_Added in 1.9.0_

*$!*

Can be used to avoid evaluating a identifier, useful in commands such as [[/timer]].

Each evaluation will remove a '!' prefix.

*Example*

<pre>
; Evaluate to $me instead of nick.
//echo -ag $eval($!me) vs $eval($me)

; Evaluate to $!me instead of $!me.
//echo -ag $eval($!!me) vs $eval($!me) vs $eval($me)
</pre>
