Error with associative array initializer

[Peter Neubauer]

I'm trying to initialize an associative array with key int and value type char[] like this:

char[][int] stuff = [
	0: "abc",
	1: "def",
	2: "ghi"
];

... which works just fine as long as the strings are all of equal length. For the following code:

char[][int] stuff2 = [
	0: "ab",
	1: "def",
	2: "ghi"
];

results in the error message "cannot implicitly convert expression ("def") of type char[3] to char[2]". Just the same thing happens if the first value in the array is of greater length than the others. It all depends on the first string. How can I avoid this?
