# Jester Partial Application Syntax

doubles = map .{ s | s * 2 }, [1,2,3]
# => [2,4,6]

# ? in arg list indicates a partial application
# in future might allow a trailing "splat" (e.g. `*?`) to indicate all remaining args have been omitted
# I don't think this precludes using ? as a ternary operator in the future either. Bonus.
doubler = map .{ s | s * 2 }, ?

Platforms

Raspberry Pi (Linux)

Huge community support. You'll get Linux working on this no problem, lots of disk images available on the web. If you're looking to integrate with hardware over GPIO, I2C, SPI, RPi is a bit limited out-of-the-box - you'll need to add something like a Gertboard to get access to a bunch of pins.

BeagleBone Black (Linux)

Strong community, but not as strong as RPi. Linux images available. Lots of pins available on the board itself with all standard microcontroller peripherals available (ADC, PWM, GPIO, I2C, SPI). Not sure how well these are all exposed to the operating system, or even what mechanisms are used to access them.
