Plotting with [Makie](https://docs.makie.org/stable/) does not work: ```julia using GLMakie f = Fun(Taylor(),[1,2,3]) lines(f) ``` I think the idiomatic way would be to define an [extension](https://pkgdocs.julialang.org/v1/creating-packages/#Conditional-loading-of-code-in-packages-(Extensions)) for Makie plots.
