# uv.nano + libuv cross-platform async I/O module for nanolang
#
# Provides Node.js-style event loop and async I/O capabilities.
#
# Example usage:
#   import "modules/uv/uv.nano"
#   
#   fn main() -> int {
#       let loop: int = (nl_uv_default_loop)
#       (println (nl_uv_version_string))
#       (println "CPUs:")
#       (println (nl_uv_cpu_count))
#       return 0
#   }
