Hi,
I'm using typeset -UT to unique a scalar variable:

export -UT CMAKE_PREFIX_PATH="$ZPFX:$CMAKE_PREFIX_PATH" cmake_prefix_path

The problem is that the variable/array will contain empty element if the
variable is empty when export is run.

I wonder if is it possible to somehow clear such empty entry (i.e.: to
remove :: from "a::b") without another line of code?
