Add prepend - the reverse of concat
natebosch opened this issue · comments
In some places it might be useful to reverse the order of concatenation to reduce nesting.
values
.transform(step1)
.transform(step2)
.transform(step3)
.transform(prepend(startingValues));
vs
startingValues.transform(concat(values
.transform(step1)
.transform(step2)
.transform(step3)));
The particular place I'm hitting this would be better solved with #19 so I'm less sure of the value here. It's also a little confusing to have prepend
and startWith
mean totally different things.
