Line numbers aren't propagating in errors

[pdeffebach]

When using @chain, line numbers are given at the level of the @chain command, not sub-commands. This makes it hard to debug. Consider the following script

using Chain

foo(x, y) = x * y

x = [1, 2]

@chain x begin
    identity
    identity
    identity
    foo([3, 4])
end

The stacktrace says the error occurs starting on line 7. This makes it hard to debug long @chains. We should try to ensure line number propogation within the chain block.

works for me in vscode:

Line number in stack trace points to foo(x, y) which is also correct

Huh. That's very interesting. I will try to explore this more. You were running from include?
