Swallowing exceptions

[teamon]

Consider the following example:

SomeMod
|> stub(:some_fun, fn _, _ -> Decimal.new(nil) end)

Here, Decimal.new(nil) should raise
** (FunctionClauseError) no function clause matching in Decimal.new/1
but what we get instead is:
** (FunctionClauseError) no function clause matching in nil.some_fun/2.

I think that's due tu this piece.
Maybe there's a way to inspect the exception and reraise if it's coming from inside stub.
