It was probably a good move for Rust and Go to go their own way, 
rather than copying others too much, in the sense that they stand 
out with one significant feature that is rare.

D should start with fixing basic problems such as not being able 
to unify types with alias. C++ is currently ahead in 
meta-programming utility IMHO. Template composition is 
foundational for meta-programming, without proper aliases it is 
just not very practical.

After that the whole memory management and "shared" topic should 
be settled in a way that bring the language some unique 
advantages.

Until that is in place there is really no use in pointing to 
minor features like string concatenation, which basically has no 
measurable impact on true system level programming or advanced 
(non-macroish) meta programming for that matter.
