Asynchronous Functions

The Quetzal Language grammar includes the reserved words asincrono and esperar to prepare for asynchronous function support. However, in version v0.0.2 these features are not yet fully implemented in the interpreter.

Reserved Syntax

asincrono texto obtener_datos() {
    // Pending implementation
}

texto resultado = esperar obtener_datos()

The above code cannot currently be executed; the interpreter will show an error indicating the functionality is not available.

Roadmap

• Functions marked with asincrono will be able to execute operations that return promises or deferred tasks.
• esperar will allow pausing the current function until the asynchronous task finishes.
• The system will respect the same type rules and error handling as synchronous functions.

Temporary Recommendations

• Implement I/O-dependent operations as synchronous functions and use native modules (e.g., quetzal/matematica) while asynchronous support is completed.
• Follow roadmap updates to know the availability of this feature.

When the functionality is released, this section will include practical examples and recommended patterns.
