Teensy 3.1 is also quite an attractive platform IMO (Cortex M4, and good
support in the Arduino IDE / environment for a while now).  Bare chip is
about £3 for integrating into OpenTRV designs.  Dev boards about £15

BTW, ARM also opens up the possibility of using a more modern language
like Rust too.

+ Resource usage of the same order as C and C++
+ No loose pointers (also lots of other compile time checks)
+ No run-time or JIT (unlike Go, Python etc.)
+ Can call C easily

... hardly done anything with it (yet), but it seems like a really nice
language, and the first practical alternative to C for embedded stuff
which I've seen IMO.

Rust on Atmel-AVR (yet) due to immature LLVM support for AVR - but it'll
probably get there at some point.
