global variable declarations not consistent?!?!
#hello_world.mojo
hello_world = 'hello_world'
def main():
print(hello_world)
print('hello_world_1')
main()
Then running on the commandline with "mojo hello_world.mojo"
Strangely, this simple program has variable output on a M1 mac laptop (MacOS 13.4.1).
Sometimes it prints
hello_world1
and sometimes it prints
hello_world1
Hello, world!
var and let both behave the same, seemingly random failure to set the variable hello_world.
Moving the line declaring hello_world into the function makes the program's output reliable, always printing both messages.
This suggests that global variables assignment does not cause an error, but randomly fails, right?!?!?
