    Zip that

    Zip that

    Merges this and that streams, creating Tuples for corresponding elements

    If that stream runs out of elements to merge, the rest of this stream will be discarded too

    (1 to 100).all.zip('A' to 'D').lp  // Prints ~((1,A), (2,B), (3,C), (4,D))

    Merge stream

    Merge stream

    Merges this and that streams, creating Tuples for corresponding elements

    ('a' to 'f').all.zip('A' to 'H', '?', '?').lp

// Output
~((a,A), (b,B), (c,C), (d,D), (e,E), (f,F), (?,G), (?,H))
    that

    the stream to merge with this

    thisDflt

    if this Stream has fewer elements, thisDflt will be used to fill the voids. Fails if thisDflt is required, but not available

    thatDflt

    if that Stream has fewer elements, thatDflt will be used to fill the voids. Fails if thatDflt is required, but not available

    Merge index

    Merge index

    Creates a new Stream with elements paired with their sequential index

    Note: Idx is the first element in the resulting tuples.

    ('A' to 'F').all.zipIdx('A'.toInt) lp  // Prints ~((65,A), (66,B), (67,C), (68,D), (69,E), (70,F))

    Merge index

    Merge index

    Creates a new Stream with elements paired with their sequential index, starting at 0

    Note: Idx is the first element in the resulting tuples

    Merge property

    Merge property

    Creates a new Stream with elements paired with their property, defined by given function

    Merge with next
