Some discussion in this thread: https://forum.dlang.org/post/mailman.206.1457557607.26339.digitalmars-d@puremagic.com

The summary is that there can be performance implications if it is necessary to copy a char[] to a string just to test for presence in the associative array. This can happen when streaming text from an input source, as it's natural to read as char[] (eg. File.byLine).

While I agree that const should be as good as immutable in this case, sometimes
it is not so clear. For example, if the key type is immutable(char[])[], should
those be accepted:
1) immutable(char)[][]  (a.k.a. string[])
2) const(char)[][]
3) const(char[])[]

BTW, http://dlang.org/phobos/std_exception#.assumeUnique can help in the mean time.
