Check Object Existence in TCL
<p>I want to check that whether object exists or not in tcl.
I looked into <code>info object</code> options but didn't found something specific for object existence and <code>info exists</code> only works for variables not objects.</p>

<p>Any idea?
I created an object of struct::stack
<code>::struct::stack aa
(Dcode) 52 % info object class aa
::struct::stack::stack_oo
</code></p>

<p>It seems that it is in tcloo.
I think in Itcl find command works <code>itcl::find object aa</code></p>

<p>But not aware of tcl_oo.</p>
