getMessage

tagGetMessage Source #

Arguments

:: (HasCallStack, MonadIO m, IsTag a)
=> a	`tag`: a `Tag`.
-> m (Maybe Text)	Returns: the message of the tag or `Nothing`.

=> a	`tag`: a `Tag`.
-> m (Maybe Object)	Returns: a `Object` or `Nothing`. (Can throw `GError`)

Recursively peel a tag until a non tag object is found.
