This library is unstable;
compatibility will not be maintained.
See Unstable for more information.
An in-syntax application can provide better performance for syntax iteration when it appears directly in a for clause.
Example: | ||
| ||
'(#<syntax:2:0 1> #<syntax:2:0 2> #<syntax:2:0 3>) |
| (in-sequence-forever seq val) → sequence? |
| seq : sequence? |
| val : any/c |
Produces a sequence whose values are the elements of seq, followed by val repeated.
| (sequence-lift f seq) → sequence? |
| f : procedure? |
| seq : sequence? |
Produces the sequence of f applied to each element of seq.
Example: | ||
| ||
'(1 2 3 4 5 6 7 8 9 10) |
