    Disallow tail calls from async functions and generators · 5af4cd98
    littledan authored
    Tail calls don't make sense from async functions and generators, as
    each activation of these functions needs to make a new, distnict,
    non-reused generator object. These tail calls are not required per
    spec. This patch disables both syntactic and implicit tail calls
    in async functions and generators.
