What's New

• give statement - needed at end of block and if expressions
• block expressions

x := {
    y := 123;
    give y-1;
};

• if expressions

x := if cond {
    y := 123;
    give y-1;
} else {
    y := 321;
    give y+1;
    };

• while loop

while cond {

}
while x := 0; x < 123 {

    x += 1;
}

• New style for loop

list := []int{1, 4, 7, 3, 7, 2, 1};
for value : list {
    fmt.println(value);
}
for val, idx : 12 ..< 17 {
    // Iterates from 12 to 16 (inclusive)
    // Optional index value: `idx`
    fmt.println(val, idx);
}
msg := "Hellope";
for r : msg {
    // r is a `rune` as this procedure iterates
    // the utf-8 string and returns the corresponding
    // codepoint or `rune` 
    fmt.println(r);
}

• New style enumerations (Most likely to change)

Byte_Size :: enum f64 {
    _, // Ignore first value
    KB = 1<<(10*iota), // 1<<10
    MB,                // 1<<20
    GB,                // 1<<30
    TB,                // 1<<40
    PB,                // 1<<50
}

• Updates to the core library to accommodate the new features

Removed Features

• Automatic semicolon insertion in favour of "mandatory" semicolons.
  • Semicolons are optional in a few cases but mainly for sanity reasons
• Nested constants from within certain records
• Increment and decrement operators: ++ --
• Capacity value in slices
  • Slices are now just a pointer and count
• append built in procedure
• capacity arguments in new_slice and slice_ptr
• enum_to_string built in procedure
  • This may come back if enumerations change their behaviour
