Merging multiple dictionaries with cell arrays

How can one merge multiple dictionaries A and B with cell arrays to get C. Ideally, with some warning for clashes.

A = dictionary( ...
    { ...
    "type", ...
    "value" ...
    }, ...
    {...
    "temporary", ...
    1 ...
    } ...
    )

A =

  dictionary (cell --> cell) with 2 entries:

    {["type"]}  --> {["temporary"]}
    {["value"]} --> {[1]}

B = dictionary( ...
    { ...
    "color" ...
    }, ...
    {...
    "blue" ...
    } ...
    )

B =

  dictionary (cell --> cell) with 1 entry:

    {["color"]} --> {["blue"]}

C = dictionary( ...
    { ...
    "type", ...
    "value", ...
    "color" ...
    }, ...
    {...
    "temporary", ...
    1, ...
    "blue" ...
    } ...
    )

C =

  dictionary (cell --> cell) with 3 entries:

    {["type"]}  --> {["temporary"]}
    {["value"]} --> {[1]}
    {["color"]} --> {["blue"]}

A = dictionary({"type","value"},{"temporary",1});
B = dictionary({"color"},{"blue"});

If you want to create a new merged dictionary without modifying the originals:

C = dictionary(A.keys, A.values);
C(B.keys) = B.values

C =

  dictionary (cell --> cell) with 3 entries:

    {["type"]}  --> {["temporary"]}
    {["value"]} --> {[1]}
    {["color"]} --> {["blue"]}

If you can modify one of the original dictionaries:

A(B.keys) = B.values

A =

  dictionary (cell --> cell) with 3 entries:

    {["type"]}  --> {["temporary"]}
    {["value"]} --> {[1]}
    {["color"]} --> {["blue"]}

You would have to experiment to find out how it behaves with duplicate keys.
