There's a class of performance bugs that you can feel. Today I inadvertently implemented "Schlemiel the Painter's algorithm", and it's obvious: performance was great at first, and then it gradually deteriorates.

Today I learnt that the Glamorous Toolkit has its own VM, implemented in Rust, which wraps the Pharo smalltalk environment!

I'm slightly surprised that Rust has implemented the Default trait for booleans: https://doc.rust-lang.org/src/core/default.rs.html#205 The default is false, but it feels very arbitrary. Maybe it makes more sense next to integers, where the default value is 0.
