struct - Dynamical access to nested fields in Matlab

(How) Can I dynamically access nested fields in Matlab? I was thinking about a test case like this one:

a = struct;
a.foo.bar = [];

place = {'foo', 'bar'};

a.(place{:})

% instead of the following, which only works if know in advance
% how many elements 'place' has
a.(place{1}).(place{2})
