Paul King commented on GROOVY-11714:
------------------------------------
It looks like you are expecting interpreter mode:
{noformat}
groovy:000> :set interpreterMode true
groovy:000> def x = 4
===> 4
groovy:000> x
===> 4
groovy:000>
{noformat}
Otherwise, variables come from the binding. Leaving off the def is how you save
them to the binding. So, the "def f" in your second example, doesn't do
anything.
> groovysh failed to store variable for grammar like 'def e = 1' for groovy 5
