Hmm, I struggle to see the logic in this example. Making easy/clear examples is hard.
Suggestion:
class ExampleTagLib {
def oncePerSession = { Map attrs, body ->
def key = (attrs.key ?: 'default').toString()
def sessionKey = "taglib.oncePerSession.${key}"
if (!session.getAttribute(sessionKey)) {
session.setAttribute(sessionKey, true)
out << body()
}
}
}<g:oncePerSession key="promo">
<div class="promo">Free shipping this week!</div>
</g:oncePerSession>

This is such an improvement already, I'm good with it. I like Mattias's suggestion on the better example too.
