Possible to use identifier construction to call proc by name (string)?

[geohuz]

Just like in python/js, we have the following proc:
    
    
    proc newAuthMessage() =
     ...
    
    proc newSubscribeMessage() =
     ...
    
    Run

and I want to call these procedures dynamically, so we have string "Auth" , 
"Subscribe", and now I need concatenate the string and call them. I tried with 
template but no luck.
