nums: i * 3 for i in [1..3]

negs: x for x in [-20..-5*2]
negs: negs[0..2]

result: nums.concat(negs).join(', ')

print(result is '3, 6, 9, -20, -19, -18')

# Ensure that ranges are safe. This used to infinite loop:
j = 5
result: for j in [j..(j+3)]
  j

print(result.join(' ') is '5 6 7 8')
using 'where' for array comprehension filtering, after kamatsu's suggestion -- execution tests pass now with significant whitespace 2009-12-29 08:52:26 -05:00			`nums: i * 3 for i in [1..3]`
added array comprehensions over ranges 2009-12-26 03:16:40 -05:00
adding a test for expressions in range comprehensions 2010-01-01 10:20:29 -05:00			`negs: x for x in [-20..-5*2]`
got negative ranges working with (much, much) uglier compiled code 2009-12-26 23:35:43 -05:00			`negs: negs[0..2]`

making range comprehensions compile safely, even when you assign to the same variable as your endposts. 2010-01-01 10:55:43 -05:00			`print(result is '3, 6, 9, -20, -19, -18')`

			`# Ensure that ranges are safe. This used to infinite loop:`
			`j = 5`
			`result: for j in [j..(j+3)]`
			`j`
