String interpolation
`text {expr} more`
A backtick string ` … is an interpolated string: any {expr} hole inside it is evaluated, converted to text, and concatenated with the surrounding literal parts. Numbers, bools, and fixed values are stringified automatically and string values pass through, so score: {score} desugars to "score: " + string(score). It is the readable way to build a message from mixed pieces without hand-writing a + chain. Write a literal brace with {{ or }}`.
Example
let status_line: string = `score {score} — health {current_health}/{maximum_health}`
Screen.status(status_line)
print(`wave {wave_number} incoming`)
