Syntax error in un-used test file

[MasonProtter]

Just an FYI, this expression : https://github.com/cgeoga/BesselK.jl/blob/main/paperscripts/testing/notinuse/matern_derivative_speed.jl#L7-L18

doesn't actually do what it seems like! Currently, writing (@foo x, @foo y) is parsed as (@foo(x, @foo(y))), not (@foo(x), @foo(y)) though changing that is currently under consideration in JuliaLang/julia#36547

Ooh, wow, TIL! Thank you for pointing this out. I suppose I should go through all of those old scripts and make sure that they still run. I could have sworn that that script also ran and did what I thought it was doing at the time, but I suppose it couldn't have.

Appreciate the heads up! I'll avoid that pattern in the future.

It was discovered by some very cool automated analysis by @c42f over in JuliaSyntax.jl!

Thanks @MasonProtter :-)

It's been on my mind to notify everyone using this surprising syntax so that (a) they can use brackets and be less surprised and (b) so that we can later change the meaning of the syntax to the expected meaning without changing anything. Clearly I haven't got around to it yet, so thanks for starting it!
