Yes, I meant that it would be a good idea to keep the modes consistent, 
and to keep those examples indent like they do now.

When you say "uses the ecma grammar", what do you mean exactly? It just 
uses the parent grammar, not either of those two?

As for copying the code, it might be fine - the indentation rules are 
difficult to share, and copying the definition of 
typescript-ts-mode--anchor-decl is probably better than loading the 
whole other package file just for its sake. If more functions could be 
reused, however...
