I do it very often.
For example this is from my recent IRC client:
try-do: func[action][if error? set/any 'err try [do action][bot-error disarm err]]
bot-error: func[err /local type id arg1 arg2 arg3][
set [type id arg1 arg2 arg3] reduce [err/type err/id err/arg1 err/arg2 err/arg3]
cprint/err [
"Bot-" system/error/:type/type ": "
reduce bind system/error/:type/:id 'arg1
]
cprint/err ["** Where: " mold err/where]
cprint/err ["** Near: " mold err/near]
]
