No. Assignments of the form
varname=( key1 value1 key2 value2 ... )
are supported where varname has previously been declared as an associative
array, but an associative array cannot be the value of an array field (as
is implied by "varname[word]=( ... )"), and the [key]=value syntax inside
the parens is not yet supported.

No, zsh does not yet support discipline functions.
} 3. I would also like to be able to use reference variables.
True namerefs in the ksh sense are also not yet supported. However, you
can get a very similar effect by using ${(P)varname}.
} [namerefs are] a little less important since it seams that zsh
} has scoping capabilities (local vs. global).
Yes, zsh supports function-scoped variables with "local"; this works a
bit like Perl's "local" in that the names are dynamically scoped (not
like "my" static scoping) but function-level is the only local scope.
