Are these intended to be interpreted modulo alpha-convertibility? (ProofPower and HOL Light both treat the assumptions as ordered sets using alpha-convertibility as the equality test when inserting and deleting elements, but I don't know about HOL4.) If the answer is no, then a reader for ProofPower or HOL Light is going to have to use some fairly horrid tricks.<br>
