Vocabulary
sequences.unrolled
Inputs
xseq
a
sequence
yseq
a
sequence
len
an
integer
quot
a
quotation
with stack effect
( x y -- newx )
Outputs
newseq
a
sequence
Word description
Unrolled version of
2map
that iterates over the first
len
elements of
xseq
and
yseq
.
len
must be a compile-time constant. If
seq
has fewer than
len
elements, raises an
unrolled-bounds-error
.
