[plt-scheme] trying not to use eval

I think I am missing something very obvious.

I want to take the value from a variable and use it as a procedure name, 
  and have it be evaluated.  I remember running across some advice in a 
text that using eval was *BAD*, but I am stumped on how to have the code 
evaluated otherwise.

Here is the snippet:

	(let ((poss (eval `(,e-type ,(car lst)))))
		...

Is there a way to do this without using eval and/or am I incorrect in 
thinking of eval as something to be avoided?

I tried without eval, and of course had what I wanted evaluated returned 
(with the values filled in).

Thanks in advance,
