Summary | TAKE does not return the same type of any-block! series being taken from |
---|---|
Description |
The result of a TAKE/PART is a series, and not a single value. However, the result of all ANY-BLOCK! TAKEs, regardless of input series, is a BLOCK!. So if you TAKE/PART from a PAREN! for instance, you get a block: >> take/part quote (1 2 3 4) 2 == [1 2] The type of the series you are taking from should be preserved, e.g. >> take/part quote (1 2 3 4) 2 == (1 2) |

Good catch!
Note, TAKE does not coalesce all series into block!s: >> take/part "foobar" 2 == "fo" >> take/part #{cafebeef} 2 == #{CAFE} >> take/part == It definitely should preserve the actual type for ANY-BLOCK! instances as well, just like e.g. COPY/part does as well: >> take/part quote (a b c) 2 == [a b] ;; Expected: (a b) >> take/part quote a/b/c 2 == [a b] ;; Expected: a/b >> take/part quote 'a/b/c 2 == [a b] ;; Expected: 'a/b >> take/part quote :a/b/c 2 == [a b] ;; Expected: :a/b >> take/part quote a/b/c: 2 == [a b] ;; Expected: a/b: |
