E118: Statements have to live inside a function

A Turf file can declare things at its top level – functions, structs, enums, imports, extern bindings, export immut constants – but it can’t do anything there. Statements (a call, an assignment, a variable, a return, an if) must be inside a function.

import io;io::printline("hello");          // a call, outside any functionfn main(): int { return 0; }

Move it into main, which is where a program starts:

import io;fn main(): int {    io::printline("hello");    return 0;}

If a file has statements at the top level because it was meant to be a script, wrap them in fn main(): int { ... return 0; }.
