I recently updated the docs to prefer the `new E[](length)` form 
instead:

At some point the `T[length]` form should be deprecated. Perhaps 
we could have a compiler switch `-strict` that deprecates a set 
of things, e.g. struct postblit. This would be used for anything 
which needs a long deprecation period and to avoid annoying 
people by adding new deprecations spread out over a number of 
releases. Instead they can update their code using the `-strict` 
check once in a while.
