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?

Best regards,
