; Basic if expressions.
if true "hello"

; These can produce values and the result bound to a name.
let a = if (2 + 2 >= 4) 42

; We support a single if expression.
let b = if (0xff == 0x32) "hello" else "world"

; ... but these can compound on each other
if      1 < 2 6
else if 1 > 2 7
else          8

; A block is an expression, and if raise the scope level regardless if a block
; is used or not.
if true != false {
    let a = "yo"
}

; Match cases should only apply to literal values, for example `case 1 + 2`
; isn't allowed. They should generally convert to a lookup table.
match a {
    case 8 = "hello"
    case 9 = "world"
    else   = "what"
}

; Enums are integers with values that increase automatically or that can be set
; with a constexpr.
enum flags {
    node_add = 1 << 0
    node_sub = 1 << 1
    node_div = 1 << 2
    node_mul
}
let f:flags = flags.node_add

; No need to qualify enum fields inside match-case.
match f {
    case node_add = "adding something..."
    case node_add = "subbing something..."
    else          = "default case"
}

; Conditional `cond` statements are syntactic sugar for a chain of if-else
; statements.
let msg:str = cond {
    a == 1 = "hello"
    a != 2 = "world"
    else   = "what"
}
