Sometimes when poking around in IEx, I will mis-pair a bracket or quote and get “stuck”. This often happens if I mispaste something.

In irb I could always just ctrl-c to basically cancel the current input buffer and put me back in the “root” of the interpreter.

irb(main):002:1* arst(
irb(main):003:1*   nieo
irb(main):004:1>
^C
irb(main):002:0>

In IEx I get this

iex(1)> arst(
...(1)> nieo
...(1)>
BREAK: (a)bort (A)bort with dump (c)ontinue (p)roc info (i)nfo
       (l)oaded (v)ersion (k)ill (D)b-tables (d)istribution

And from my poking around, a/A quit IEx, c puts me back where I was, p,i,l,v,D,d,k are informational or for killing processes (maybe the current IEx is hidden in there).

Is there a way to just throw out all the current input (short of working out what pair is open and manually closing them all)? I want to retain the rest of my IEx state.
