In #53821, scrub_repl_backtrace was changed to scrub frames starting with __repl_entry, a new creation for the REPL module, rather than matching :eval.

The impact of this change is that traces originating from the fallback client.jl REPL are no longer successfully scrubbed, because it refers to a REPL stdlib function. It also means Base client.jl code is depending on a REPL stdlib implementation.

Some options:

• client.jl implements and uses __repl_entry... functions instead of REPL.jl
• client.jl mirrors REPL.jl with its own e.g. __client_entry... and duplicate scrub_repl_backtrace
• scrub_repl_backtrace could accept an argument for the string to match to make it generic, so there could be a default for client.jl and REPL could provide an override.
