[stringtemplate-interest] Re: cminus.g

[Laurent Vaucher]

   Well, the way I understand the difference between program, which  
returns a value, and declaration, which takes a stringtemplate as a  
parameter is the same as between a 'purely functional' function and a  
'side-effect' one. The second is used to 'fill' an already existing  
object with additional data.
   It might be possible to convert the whole thing to a 'purely  
functional' style, but I think one point of the article was to show  
all the possible approaches with the library. The other possible  
explanation is 'purely pragmatic': do the simplest thing that might  
possibly work ((c) Ward Cunningham). If one style is simpler to use  
in some cases, just use it.
