Important is, of course, in the eye of the beholder.

I for one would not use tcsh or zsh.  I use bash under cygwin
rather than pdksh.  But that is only because ksh is not available.
In all other environments ksh is my default.  That is the main
importance of having it available under cygwin (to me).

As to explicit features lacking in bash (and/or others) I might include:

	floating point math
	non-posix functions with local environments
	a function PATH variable
	several special substitution capabilities like ${!array[*]}
	  which lists the current subscripts of array

Any proficient bash programmer may be able to point out my errors and
list lots of things bash has that ksh lacks.  And probably several will :(
