we enter a debugger via builtins.break in the input file.
|
|
|
|
info: breakpoint reached
|
|
|
|
causing another debugger even should not nest, but simply
|
|
print the error, skip the breakpoint, etc as appropriate.

"values show"

nix-repl> builtins.break 2

nix-repl> builtins.throw "foo"
|

error:
|

… while calling the 'throw' builtin

exiting the debug frame should allow another to open.
