curious behaviour - disappearing variable scope

by Ben Coman

I'm curious about the following behaviour... "In Playground, first evaluate..." s := Semaphore new. [ [ s wait. Transcript crShow: 'x' ] whileTrue ] fork. "then later..." s signal. ==> 'x' is seen in Transcript but then an error pops up "#wait was sent to nil" So... 's' *was* valid and then its not? cheers -ben

It requires the download of an external resource, always a bit tricky ... And although PngSuiteExplorer is really nice, just downloading the .zip and gt inspecting a file reference to it gives you a big part of the same functionality for free (as the .png are shown).
