Regarding `println`: since it has multiple methods, you cannot find _the_ definition. Eg `methods(println)` should list them all.

That said, overwriting a method in `Base` is almost surely not the way you want to do this. I asked a similar question a while ago, you may find the solution helpful:

This can lead to very long output in the REPL, which not all terminals and interfaces are happy with. I am wondering it it would be possible to somehow customize the REPL or the display infrastructure to catch this. Eg when working the REPL, somehow impose a sanity check of cutting off at eg line 100,…

Or, if this is not for display purposes, you can define a wrapper type for an `<:IO` that captures the `\n`, and flushes. This is a nice example of something similar:
