The syntax tree is only the first half of the syntax story. The second half happens in lowering, and that’s where the magic occurs:

```julia
julia> Meta.@lower z=x.*y
:($(Expr(:thunk, CodeInfo(
 1 ─ %1 = (Base.getproperty)(Base.Broadcast, :materialize) │
 │ %2 = (Base.getproperty)(Base.Broadcast, :broadcasted) │
 │ %3 = (%2)(*, x, y) │
 │ %4 = (%1)(%3) │
 │ z = %4 │
 └── return %4 │
))))

```

This belies a good deal of complexity, but that’s the entrance to the rabbit hole.
