working on a home made scripting language - name suggestions?

main.rs

fn set_x(a: 'return, val: 'a) -> {
    a.x = val
    return val
}

fn main() {
    y := {x: {0: 0}}
    set_x(y, {0: 2}) // ERROR: Requires reference to variable
    println(y)
}

Some info about the language (mix of Rust, Go and Javascript):

• Just developed for fun right now
• Using Piston-Meta for parsing, so people can change the syntax without recompiling
• Goal: To develop a scripting language that is ordinary - specifically avoiding weird or fancy stuff
• Does not use a garbage collector yet - uses lots of .clone() though and can unsafely return local variables inside objects
• Might be able to use fn foo(a, b: 'a) { ... } for borrow checking to avoid unsafe code
• If borrow checking is added, fn foo(a: 'return) -> { ... } means a is a reference that outlives the return value
• Go like for i := 0; i < n; i += 1 { ... } loops and := for variable initialization and = for mutable assignment
• Dynamically typed, similar to Javascript: Arrays [1, 2, 3] and objects {x: 0, y: 0} (however, = expects same type)
• Function declaration similar to Rust fn foo() -> { ... }
• Variable name shadowing like in Rust
