`bflat` happily compiles a program without `Main` method about bflat HOT 2 OPEN

bflat considers things without Main libraries and that's a feature, not a bug. I'll leave this open because the compiler could generate a warning if there's no UnmanagedCallersOnly methods with an entrypoint (the library is a non-sensical library, but it is a library nonetheless).

This app can't run on your PC - the output should have a .dll extension in this case. One needs to go out of their way to rename the file to get this failure mode.

This is bflat's weirdness. I will note this. Thank you.

Again, this is bflat's weirdness. Only bflat requires me to specify the executable name with extension, otherwise it will output an extension-less file. All other compilers choose the extension for the executable automatically.
