I recall that Andrei has mentioned plans on further DMD 
optimizations that will delay lexing and/or parsing of templates 
until they are referenced. Only the matching ending brace of the 
template definition will be searched for during the primary 
scanning of each source file. The rest is cached as a strings 
associated with the corresponding template symbol until it is 
referenced/instantiated.
