<range> | (<seq.>) | C |
|
range-by | (from|<num> test|<fun> lim|<num> by|<fun>=> <range>) | G |
|
| returns a range starting from, updated with by,
and continuing until (test x lim) is false. | |
|
range | (from|<num> test|<fun> lim|<fun> => <range>) | G |
|
| == (range-by from test lim (op + _ 1)) | |
|
from | (from|<num> => <range>) | G |
|
| == (range from (always #t) 0) | |
|
below | (lim|<num> => <range>) | G |
|
| == (range 0 < lim) | |
|
<step> | (<seq.>) | C |
|
| Steps represent step functions. | |
|
first-then | (first|<fun> then|<fun> => <step>) | G |
|
| returns a new step object, calling thunks first to retrieve
initial value and then to retrieve subsequent values. | |
|
each | (f|<fun> => <each>) | G |
|
| returns a new each object, calling f thunk to retrieve
each value. | |
|
<cycle> | (<seq.>) | C |
|
| Cycles provide a mechanism to create infinite sequences repeating
a certain sequence over and over again. | |
|
cycle | (x|... => <cycle>) | G |
|
| returns a cycles that repeats elements of x. | |
