Support typed parameters inside unions

Note: this is my first time working with the internals of MacroTools. I may have done something wrong. I'd appreciate as much review attention as you can spare. This supports...

Match failure when combining Unions and expression types

2

It appears that attempting to create an `@match` that uses unions and expression types results in no matches being found. A few examples: This works: ```julia julia> @match :(x[1]) begin...

Cross-posted from https://discourse.julialang.org/t/nesting-forwarddiff-inside-reversediff/3684/3 The following (possibly ill-advised) nesting of ForwardDiff inside ReverseDiff fails: ```julia f = (x, w) -> sum(x .* w) g = (x, w) -> ForwardDiff.gradient(x -> f(x,...

I noticed while playing around with the updates to MeshCatMechanisms that the spatial inertias in all of the simple examples are set to something like `I * axis * axis'`....

Similar to #96, constructing an `AngleAxis` from a `UnitQuaternion` produces `NaN` derivative elements when using `ForwardDiff`: ``` julia> using Rotations julia> using ForwardDiff: Dual julia> q = UnitQuaternion(Dual(1.0, 0.0), Dual(0.0,...

NaNs when using ForwardDiff with RodriguesVec

For example: ```julia julia> using ForwardDiff, Rotations julia> ForwardDiff.derivative(0) do x rotation_angle(RodriguesVec(x, 0, 0)) end NaN ``` This comes out of the way the rotation angle is computed, which involves...

I'm afraid I have absolutely no idea why, but adding this line to `runtests.jl` causes the test to crash: ```julia msg = Message("hello") ``` with the error message: ``` Assertion...

Default methods for `terms()` and `polynomial()` create an infinite recursion

I just noticed that if you create a custom type `MyPoly

Segfault in figure() when package Gtk imported
