In Julia 1.2 with an unknown but presumably up-to-date version of Plots, I wrote

`plot([cos sin])`

to get cosine and sine plots from an adaptive plotter. Yesterday I upgraded to Julia 1.4 and now apparently Plots version 1.0.3 and this fails. I now must write

`plot([cos, sin])`

(note the comma).

Furthermore, I now must use the inconsistent form

`plot([cos, sin], color = [:red :blue])`

.

Was I smoking something I wasn’t supposed to?
