Synopsis

Usage:

toSequence x
Inputs:
- x, a basic list or a string, or an instance of a class with the iterator method installed
Outputs:

toSequence x yields the elements of a x as a sequence.

i1 : toSequence {1, 2, 3}

o1 = (1, 2, 3)

o1 : Sequence

i2 : toSequence "foo"

o2 = (f, o, o)

o2 : Sequence

i3 : toSequence iterator {1, 2, 3}

o3 = (1, 2, 3)

o3 : Sequence

If x is already a sequence, then x is returned.

i4 : toSequence (1, 2, 3)

o4 = (1, 2, 3)

o4 : Sequence
