Recently Erlang language has added several things:

One interesting change is the syntax to handle associative
arrays (that are meant to be used a little like records):
Updating a map is done as follows:
NewX = X#{ key1 => Val1, ... KeyN := ValN, ...}
X is the old associative array. "=>" adds a mew key, while ":="
updates an already existing key, and if it's not present an
error is generated. So a spelling mistake cannot accidentally
introduce a new key if you want to update some value. This
avoids a common mistake.
I am not suggesting to add a new syntax to D, but perhaps a
simple "AA.update(key, val)" function in the object module can
be useful.

AA[key] = val; ?
