Prints won't show up when debugging a function

[johnh]

As an aside, I recently asked a question about using prints for debugging, similar to Python debug

The answer was to look at
https://docs.julialang.org/en/v1.1/stdlib/Logging/#Environment-variables-1

and

@assert alternatives?

+1 for outside-the-box we want the assertion macro to be able to dissolve in a released version we do not want to force the package user to start with --check-bounds=no reversing the sense of your macro forces bounds checking off when assertions are active, and that is imperfect for development fwiw years ago I found a way that worked – would be worth more with sourcetext, and maybe it worked by using aspects of very early Julia that no longer hold.

Equivalent of Python if __debug__

In Python there is a feature for simple print style debugging to be switched on or off. If you run a Python script with the -O option then if __debug__: print variable, variable, variable Is there an equivalent in Julia? I know you could set a constant to be true or false, bt that involves editing the code to switch on/off the debug lines.
