OS: MacOS Mojave 10.14.6 (18G87)

Both 'Save File and Run' and Command window run script, that will happen.

This example works for me on GNU/Linux.

@apjanke Can you confirm this on an otherwise working macOS build?

Is this specific to the GUI? Is this specific to running a script in the GUI editor with F5 (Save File and Run)?

Block Comments really 'block' everything!

Just run a simple script:


block comment



We will hang, nothing output, memory will be used out.
