Member FApp::GetName (): need better application name discovery. this is quite horrible and may not work on future platforms.
Member FExpressionNode::FExpressionNode (T In, typename TEnableIf<!TPointerIsConvertibleFromTo< T, FExpressionNode >Value >::Type *=nullptr): : make this a default function template parameter when VS2012 support goes
Class FInterpCurve< T >: Docs: FInterpCurve needs template and function documentation
Class FInterpCurvePoint< T >: Docs: FInterpCurvePoint needs better function documentation.
Member FLinearColor::Quantize () const: deprecate me
Struct FStackWalkModuleInfo: , the memory profiler should not be using this as platform agnostic
Struct Impl::TGetOperatorCallPtr< T >: : decltype(&T::operator()) can go directly in the specialization below if it weren't for VS2012 support
Class TBigInt< NumBits, bSigned >: : optimize Data is stored as an array of 32-bit words from the least to the most significant Doesn't handle overflows (not a big issue, we can always use a bigger bit count) Minimum sanity checks. Can convert from int64 and back (by truncating the result, this is mostly for testing)
Class TRangeSet< ElementType >: gmp: Implement more efficient storage of range sets
Member TRangeSet< ElementType >::Overlaps (const TRangeSet &Other) const: gmp: This could be optimized to O(n*logn) using a line sweep on a pre-sorted array of bounds.
Struct UE::Math::TIntPoint< InIntType >: Docs: The operators need better documentation, i.e. what does it mean to divide a point?
Struct UE::Math::TIntRect< InIntType >: Docs: The operators need better documentation, i.e. what does it mean to divide a rectangle?
Member UE::Math::TQuat< T >::CalcTangents (const TQuat< T > &PrevP, const TQuat< T > &P, const TQuat< T > &NextP, T Tension, TQuat< T > &OutTan): document
