@use_file get stuck in a loop when used in list-comprehension

[MrHenning]

When I watch files using @use_file, the cell-evaluation repeats indefinitely:

Or in code:

# ╔═╡ d897134c-3905-49c9-bc67-cf65252fc18e
begin
	f1 = tempname()
	open(f1,"w") do io
	   println(io, "test1")
	end
end

# ╔═╡ da80d3e9-0141-4f27-b6b8-da70abc77fbc
begin
	f2 = tempname()
	open(f2,"w") do io
	   println(io, "test2")
	end
end

# ╔═╡ 71e01590-0310-40fa-97c3-3aea48c20ae4
[@use_file(f) for f in [f1,f2]]  # <-- this cell re-evaluates indefinitely

# ╔═╡ 2902b855-2289-44b0-b53b-41841be6c806
[@use_file(f1), @use_file(f2)]  # <-- this cell evaluates once

I guess that's due to a closure in the list-comprehension?

I looked into the @use_file, but didn't find any way to fix this. Maybe @use_file is just not supposed to be used like this, then one could use something @assert isfile(eval(filename)) in @use_file to "warn" users?

The issue is that Pluto Hooks are currently written with the hypothesis that each macro call is run only once per cell execution.
