Broken on Julia nightly

[lassepe]

For https://github.com/JuliaLang/julia/commit/e3de4a86c795ea64bcc0b0c0ab677485e7b4efc7 I can no longer load this package. I'm seeing the following error

Precompiling project...
  ✗ LazyAlgebra
  0 dependencies successfully precompiled in 1 seconds. 20 already precompiled.
  1 dependency errored. To see a full report either run `import Pkg; Pkg.precompile()` or load the package
