like_having() for active record

[eluser]BlueCamel[/eluser]
Can we get a like() function for the HAVING clause in active record? Maybe we could rename the existing or_like() and like() to or_where_like() and where_like() then add or_having_like() and having_like() functions?

I'm not sure about SQL standards, but in MySQL at least it's perfect valid to write HAVING col like '%foo%'.
