Does the following count as a fragile hack? (Probably yes!)
macro run(file, args...)
args = [file, args...]
return esc(:(ARGS = map(string, $args)[2:end];
include(string($args[1]))))
end
julia> @run test.jl a b c
a
b
c
Though you must do
julia> @run "/Users/david/test.jl" a b c
a
b
c
with quotes, which is what I guess you referred to with "parsed form"?
