Dictionary with key-value pair of string ---> string array?

Using the older containers.Map object, I can map a string to a string array:
keySet = ["Jan";"Feb";"Mar"];
valueSet = {["New Year","MLK"]; ["Valentine's","Presidents'"];[]};
M = containers.Map(keySet,valueSet);
M("Jan")
ans = 1x2 string array
"New Year" "MLK"
I have not found a way to make a similar mapping via the newer dictionary object (even though the documentation states that a dictionary is preferred "because it supports more data types as keys and values and provides better performance").
Maybe I'm overlooking something. Any suggestions are appreciated.

Hi cyclist,
Do you mean mapping to the string array contained inside the cell?
keySet = ["Jan";"Feb";"Mar"];
valueSet = {["New Year","MLK"]; ["Valentine's","Presidents'"];[]};
d = dictionary(keySet,valueSet)
d = dictionary (string --> cell) with 3 entries: "Jan" --> {["New Year" "MLK"]} "Feb" --> {["Valentine's" "Presidents'"]} "Mar" --> {0x0 double}
d("Jan")
ans = 1x1 cell array
{["New Year" "MLK"]}
d{"Jan"}
ans = 1x2 string array
"New Year" "MLK"

I could have sworn I tried that exact syntax! sigh
Thanks for the answer.
