Function undefined for @btime when using for loop

[bojeryd91]

Unlike @time, @btime throws an error that fun is undefined when I run

using BenchmarkTools
f(x) = x^2; g(x) = x^3; h(x) = x^4
@btime f(2.0) # This works

for fun in (f, g, h)
    @time  fun(1.0)
    @btime fun(1.0) # This throws UndefVarError: fun not defined
end

I am running BenchmarkTools v1.3.1 and Julia 1.6.0

Note that it works if you interpolate $fun, which is the right thing to do anyway. But it still shouldn't error without interpolation
