Try finally when opening a file
Hi all, the following code:
fn main() raises:
var file: FileHandle
try:
file = open("my_file.txt", "r")
print(file.read())
finally:
file.close() # =>error: use of uninitialized value 'file'
gives an error in the finally clause. Adding except doesn't help.
Why is file not visible in finally? Thanks!

Is there a way in Mojo to know the type of a variable/object ?
Something like type() in Python. If not, is this useful and/or on the roadmap?

Mojo in the Tiobe-index
Arguments can be made about the usefulness of the Tiobe index, but the measure of Mojo's popularity in it grew from #184 in Nov 2023 to somewhere in the range from #51 to #100 in Jun 2024 (the index doesn't specify the position in that range).
This is an amazing growth-rate in only 7-8 months, many interesting languages (for example Pony) never made it that far. Mojo certainly has the potential to raise to the range 20-50 (where we will know the exact position) and beyond, we'll notify you when it does.
