array of structures to cell array via comma-separated list

Suppose I have the following array of structs:
data(1).f1 = 1;
data(2).f1 = 2;
data(1).f2 = 'foo';
data(2).f2 = 'bar';
And I want to put each struct into one cell of a two-element cell array:
struct_as_cell = arrayfun(@(x) x, data, 'UniformOutput', false);
Is there any easier syntax to do this? I would have hoped that data(:) would generate a comma-separated list of structs so that I could do the following, just as I could if data was a cell array, but it doesn't seem to work:
struct_as_cell = {data(:)};
Cheers

Cedric, the purpose is in order to use struct_as_cell as the valueSet for constructing a containers.Map . Unfortunately it seems that you cannot use arrays of structs directly as containers.Map valueSets, you have to convert them to this form (cell arrays of scalar structs).
Azzi, I was just hoping that there might be a simpler syntax to do this instead of using arrayfun :)

Ah! I just learned something from Azzi's answer with num2cell().

for k=1:size(data,2)
out{k}=data(k)
end

Very good Azzi, I didn't even think of num2cell because I've only used it for numeric arrays! :)
