Compare the simple and wrong syntax with the correct but verbose syntax:

a = [[]] * 4

b = [ [] for _ in range(4) ]

In Toit you pass a block (small fn introduced with a colon) to the List constructor.

c := List 4: []

Going to ban this space-less function call. We need this syntax for raw strings.

Took an immense amount of self discipline and focus, so yesterday ends(at 1am today) with an esp32 running a @toitlang container with capacitive moisture sensor sending moisture levels every 3 seconds to a local mqtt broker on a raspberry Pi which I can look at through my phone.

Looks like we picked the right day to have a PNG reader that's 100% written in a memory safe language.

Looks like we picked the right day to not have UEFI -- or a BIOS for that matter https://t.co/BqTLxFAcgm

New version of @toitlang's pixel_display library is getting sliders. We have PNG support, but no PNGs were used here, just gradients like the ones we know from the web.

Version v2.0.0-alpha 118 is released with support for weak maps and watchdog timers.

Our friends from @toitlang have just released a new tutorial for Walter, our powerful ESP32-S3 development board with LTE-M, NB-IoT, and GNSS. https://t.co/LpksrOm3Uz

Going to launch soon on @crowd_supply. 🙌https://t.co/bzDbtgvMbl💪 #Walter #IoT #Toit #IoTDevelopment

In the Toit weak map proposal the lifetime of the key is not relevant, so it can be a string or an int, but the value can be automatically removed from the map if it is not otherwise reachable and we need the memory.

[The Toit Language @toitlang]

Looks like I'm getting weak maps, but not with the JavaScript semantics.

In JavaScript WeakMap the key keeps the value alive, but when the key is collected by the GC, the key-value pair are removed from the map, and the value may become GC-able.

[Erik @erikcorry]

I decided I needed a weakly retaining hash map for my latest #toitlang project. It can be used to cache values that can be recalculated. The values can be nulled out during GC if the objects are not reachable in other ways and there is memory pressure.
