Yes. Here are a few examples from one of my dialplans:

; invalid template
[i](!)
         exten = i,1,                    verbose(1,[${EXTEN}@${CONTEXT}])
         exten = i,n,                    goto(${CONTEXT},s,1)

; look up (set) DNIS (DID) channel variables
         exten = _x.,n,                  goto(lookup-dnis,${EXTEN},1)

; dispatch to selected application
         exten = _[123456],n,            goto(${PRODUCT-${EXTEN}-APPLICATION},s,1)

This particular dialplan uses the invalid template in around 30 contexts 
and 'goto(${CONTEXT},s,1)' about 15 times. Note that the last example 
'nests' the variable expansion -- a variable within a variable.
