need express output equivalent to #[ ] when using #run instead of #call

[kevinburleigh75]

When calling a lev routine at the top level, one can replace:

value = RoutineName.call(...).outputs.value

with:

value = RoutineName[...]

if :value is an :express_output of the routine.

When calling one lev routine from inside another using #run, there is no equivalent syntax to avoid:

value = run(RoutineName, ...).outputs.value
