Is it possible to create a custom control structure with several code blocks, in the fashion of before { block1 } then { block2 } finally { block3 }
? The question is about the sugar part only - I know the functionality can be easily achieved by passing the three blocks to a method, like doInSequence(block1, block2, block3)
.
A real life example. For my testing utilities I'd like to create a structure like this:
getTime(1000) {
// Stuff I want to repeat 1000 times.
} after { (n, t) =>
println("Average time: " + t / n)
}
