#
# What this teaches:
#   • Explicit type arguments at function and namespaced call sites.
#   • Related keywords: functio, tensor, typi-parametri
#
# Common mistakes:
#   • Type parameter not satisfying the function's bounds — explicit type arguments must meet any constraints declared on the generic function.
#
# See also: functio, tensor, typi-parametri

# EXPECTED OUTPUT:
#   creata
#
# Application lane (`faber check` / `faber build` / Rust emit). Default
# `faber run` / script stepper do not yet lower explicit call-site type args.

fn identitas<T>(T x) → T {
    return x
}

main {
    print identitas<string>("creata")

Expected output:

creata
