I'm not experienced in this whole area, so I meant to ask in an open ended way :) Does uLisp play well with sleep modes and setting up interrupts to come out of sleep and stuff? I've been wanting to build a lower power weather logger that can run on a battery for a year. While scoping out the difficulty of the project and digging into lower power stuff .. things got very hairy very fast (this was with STM32F1 chips). A GC seems like an added layer of complexity. Like what happens if you have garbage collection during an interrupt handler? Or if your garbage collection is interrupted by something else..? is garbage collection on its own timer/handler that you need to manage? Or is this built on top of the Arduino main-event-loop based model of programming? In which base it doesn't seem to be the normal interrupt driven thing you'd be looking at for lower power applications.. i think
