REPL shell mode string interpolation on 0.6 RC2

Internals & Design

Has there been an intentional change to string interpolation in the REPL shell mode (I can’t see anything in NEWS.md)?

On v0.5.1:

shell> echo $("hello world")
hello world

On v0.6.0-rc2.0:

shell> echo $("hello world")
$(hello world)

That is unintentional – can you file and issue and ping me in it, please?

Thanks Stefan, please see #22176.
