Description

class Tester {
static main(args) {
c = 0

{ c = 9 }
println(c)
}
}

prints 0

This is because the code in curly brackets is treated as a closure not as a block.

If I write

class Tester {
static main(args) {
c = 0
if (true) { c = 9 }

println(c)
}
}

then it prints 9

The behaviour of the compiler isn't really a bug but it is surprising behaviour to a C or Java programmer.

I can see no use for the construction and immediate discarding of a closure. Would it be possible for the compiler to treat this construct as a block?
