Generally, inside a _(), xgettext expects to see one string and extracts
it. This is not 100% identical with the semantics of the programming
language, but is transparent enough so that you can play nice tricks
with it. Such as
    _(false ? "literal string" : decrypt("encrypted literal string")).
So a change in this area would have benefits _and_ drawbacks.

There are several workarounds in your case: move the access to a
function, such as
   function monthname(x) { return _(\$a[x]); }
- sorry if I didn't get the PHP syntax right - or assignment of the
index to a variable outside the _().

No, it will not be fixed, because as said above, there are reasonable
use cases of lax syntax checking.
