Well I'm having similar difficulty with version 1.10.  I know I can get
the above example to work by using a function instead.  For example

function xx () { echo abc $1 def };

But if I try to declare a environment variable within the function, the
variable vanishes after the function completes.  This is contrary to the
statement that functions execute each line within the same shell.  For
example if try to declare a function to simplify setting by X-Windows
DISPLAY variable like so:

function xdsp () { declare -x DISPLAY=$1:0.0 }

This happens:

declare -x DISPLAY=foo
xdsp lumpy
echo $DISPLAY
foo

Any ideas, or is this just a feature of Bash?
