[jira] Created: (BOO-1071) List comprehension cannot be used inside array constructor

List comprehension cannot be used inside array constructor
----------------------------------------------------------

                 Key: BOO-1071
                 URL: http://jira.codehaus.org/browse/BOO-1071
             Project: Boo
          Issue Type: Bug
          Components: Compiler
    Affects Versions: 0.8.2
            Reporter: Sami Kyöstilä
         Attachments: array-init.boo

Using a list comprehension with an array initializer fails with a type error, e.g:

a = array(short, [i ** 2 for i in range(10)])

==>  BCE0022: Cannot convert 'Array-initModule.Main$2' to 'short'.

The following workaround does work, but it seems like the first form should work too:

l = [i ** 2 for i in range(10)]
a = array(short, l)

Bonus wish: Allow for array comprehensions where the above would simply be (i ** 2 for i in range(10)).

---------------------------------------------

Array comprehensions are written like this in boo:

    array(i ** 2 for i in range(10))
