Inspired by mirai, I'm experimenting with using `[]` as an alias for `cdo_execute()` to run the deferred execution in rcdo. This works well when doing just one operation.
Instead of
```
cdo_sub(forecast, obs) |>
cdo_execute()
```
You can do
```
cdo_sub(forecast, obs)[]
```
Which is much shorter.
@klmr That would make composition harder, things like
```
cdo_sub(file1, file2) |>
cdo_sqr() |>
cdo_mean() |>
cdo_execute()
```
Would be harder to make work if cdo_ functions returned functions.
@eliocamp Hmm not sure what you mean, `|>` works fine with higher-order functions. Here’s some dummy code which makes your pipeline work:
cdo_sub = function (a, b) {
\() a + b
}
cdo_sqr = function (x) {
\() {
r = x()
r * r
}
}
cdo_mean = function (x) {
\() mean(x())
}
cdo_execute = function (x) {
x()
}
file1 = 1 : 5
file2 = 2 : 6
cdo_sub(file1, file2) |>
cdo_sqr() |>
cdo_mean() |>
cdo_execute()
(In real code you’d force() the args first.)
