Great moments in code reuse:
def isRootOrEmptyPackageClass(s: Symbol) = s.isRoot || s.isEmptyPackageClass
def isRootOrEmpty = (this == EmptyPackageClass) || (this == RootClass)
def isEffectiveRoot = isRoot || isEmptyPackageClass
// last one actually not quite identical
def isUnqualified(n: Name) = n match { case nme.ROOT | nme.EMPTY_PACKAGE_NAME => true ; case _ => false }
I was responsible for at least half of these. Now it's only
isEffectiveRoot.
Also, I have always found it warty that we have to specify Nothing
and Any as upper bounds. I gave the TypeBounds companion object a few
obvious methods:
def empty: TypeBounds = apply(NothingClass.tpe, AnyClass.tpe)
def upper(hi: Type): TypeBounds = apply(NothingClass.tpe, hi)
def lower(lo: Type): TypeBounds = apply(lo, AnyClass.tpe)
It's a lovable patch. No review.
