This is still reproducible in the playground as of today. The kernel reliably crashes on simd_width 16 and above and not at 8. Click to see updated code ```python from...

cc @River707 @walter-erquinigo getting a crash trace from the playground would be useful here.

It's not "intended" to be a limitation, but it is a current limitation.

@willghatch fixed this! This in the next release you will be able to access declarations outside structs.

The code you have shown will work in Mojo. In Mojo, implicitly declared variables are function-scoped, and implicitly declared variables are only allowed inside `def` functions. Explicitly declared variables with...

We don't have multiple scoping rules for different "kinds" of variables, but rather it's where we choose to place implicitly declared variables. The rule is that implicitly declared variables are...

As a statically compiled language with initialization guarantees, Mojo will never perfectly match the behaviour of Python when it comes to dynamic initialization. In addition, the code you showed will...
