RIGHT_PBETA
PairRules.RIGHT_PBETA : (thm -> thm)
Beta-reduces a top-level paired beta-redex on the right-hand side of an equation.
When applied to an equational theorem, RIGHT_PBETA applies paired
beta-reduction at top level to the right-hand side (only). Variables are
renamed if necessary to avoid free variable capture.
A |- s = (\p. t1) t2
---------------------- RIGHT_PBETA
A |- s = t1[t2/p]
Failure
Fails unless the theorem is equational, with its right-hand side being a top-level paired beta-redex.
