Type boxed unexpectedly

[BioTurboNick]

From: JuliaPlots/PlotUtils.jl#119

Changing i = findlast(t -> t < x, v) to i = findlast(<(x), v) here greatly improved performance because the former caused the function to box x.

Seems like they should be equivalent?

x is assigned to multiple times, so this is another instance of #15276.
