How to dynamically pass operators to if?

Hi,

I have a situation where I'm trying to pass the comparison operator
dynamically to a conditional. Something like this,

proc myproc { args } {
   # pull out of args what I need which, among other things will be
   # a couple of values for a comparison operation in an if conditional

   if { $val1 $oper $val2 } {
      # do lots of important stuff
   }
}

when this executes, I get this error.

syntax error in expression " $val1 $oper $val2 ": extra tokens at end of
expression

So, how would I make this happen?
