Why does CharSequence not have String getChars(int srcBegin, int srcEnd, char[] dst, int dstBegin)

[Paulo Levi]

Can't be changed? No user of the api is currently using getChars on a
Charsequence (because it doesn't exist!)

If you're talking about other implementers of Charsequence than the
jdk, well, i don't see why do we have to suffer ignominious interface
incompleteness just because someone doesn't want to compile the code
ever again.

And couldn't it be made to work anyway?
