Nuprl Rule : callbyvalueExceptionCases

This rule proved as lemma rule_cbv_exception_cases_true in file rules/rules_cbv_exception.v
at https://github.com/vrahli/NuprlInCoq

H  ⊢ a = b ∈ T

  BY callbyvalueExceptionCases x t y.u ()

  H  ⊢ is-exception(eval y = t in u)
  H x:(t)↓ ⊢ a = b ∈ T
  H x:is-exception(t) ⊢ a = b ∈ T
  H  ⊢ t ∈ Base

Definitions occuring in rule : callbyvalue: callbyvalue, has-value: (a)↓, is-exception: is-exception(t), equal: s = t ∈ T, member: t ∈ T, base: Base, axiom: Ax
