Known issues

Due to the simplicity of the current lookahead scheme, there are some limitations:

Parentheses and brackets must open on the same line as the item they're opening.

Curly braces work fine, though.

✅ Works:

export log: func(
	msg: string
) -> result<
	_,
	err
>

❌ Broken:

export log: func
(
	msg: string
) -> result
<
	_,
	err
>

Return type annotations must start on the same line as the closing parenthesis of the parameter list.

✅ Works:

export log: func(msg: string) -> result<_ err>

export magic: func(
	a: u32,
	b: u32
) -> (
	c: u32,
	d: u32
)

❌ Broken:

export log: func(msg: string)
	 -> result<_ err>

export magic: func(
	a: u32,
	b: u32
)
->
(
	c: u32,
	d: u32
)
