    Walk over tree applying a Task while checking for semantic errors.

    This is how Java is generated from an abstract syntax tree: the Task in that case is JVMCompiler.

    task

    generic task to perform on this abstract syntax tree node's context

    symbolTable

    used to look up symbols, cells, and pools

    functionTable

    used to look up functions

    engineOptions

    implementation options

    version

    version of the PFA language in which to interpret this PFA

    returns

    (information about this abstract syntax tree node after type-checking, result of the generic task)
