"Words must not leave objects on the retain stack, nor expect values to be there on entry. The retain stack is for local storage within a word only, and occurrences of " { $link >r } " and " { $link r> } " must be balanced inside a single quotation. One exception is the following trick involving " { $link if } "; values may be pushed on the retain stack before the condition value is computed, as long as both branches of the " { $link if } " pop the values off the retain stack before returning:"
