A small fix for this small problem is to just say in the specification 
that heredoc identifiers may not exceed 1e100 characters. ;)

Another fix could be to just go over the language specification and 
replace all wrongly applied CS terms by a short explanation of what is 
actually going on. (In practice, when Walter says D's grammar is 
context-free, what he means is that parsing does not depend on semantic 
analysis on a prefix of the code, a property that C++ has which implies 
context-sensitivity and is usually abbreviated this way, and Walter's 
aim was to contrast D to this.)
