If you do something like:
include("file_with_missing_dependency.jl")
you get a warning like:
ERROR: LoadError: LoadError: UndefVarError: SomeUnloadedVar not defined
Stacktrace:
 [1] include_from_node1(::String) at ./loading.jl:569
 [2] include(::String) at ./sysimg.jl:14
 ... // wherever you called include from
If you wrap the include() in a try-catch, you get some more information, namely:
cur_error = {
    "file" => "/Users/.../file_with_missing_dependency.jl",
    "line" => 42, # whatever line has "SomeUnloadedVar"
    "error" => {
        "var" => :SomeUnloadedVar
    }
}
Is there a way to get the stacktrace inside the file being loaded?
Like exactly how nested is that 42.
Is it relatively decoupled like this:
41
42  dummy_var = SomeUnloadedVar.rand()
43
or the much more tangled scenario:
30  for i in 1:10
...    dummy_var = ( 1 + 
41              SomeUnloadedVar.rand()
42     )
43     ... 
summarizing. would it be possible to find the line value of 30 in the above code block?
