## Description

Yaegi is a Go language interpreter and embedded scripting engine that executes Go source code at runtime without requiring a separate compilation step. It provides a mechanism for evaluating Go expressions and files dynamically, functioning as both a library for compiled applications and a standalone read-eval-print-loop environment.

The project enables the integration of dynamic Go scripts into compiled programs to allow for runtime extensibility and plugin development. It facilitates the conversion of interpreted symbols from evaluated scripts into usable interfaces and types within a compiled program.

The system covers dynamic code evaluation, package loading, and interactive prototyping through a command-line shell. These capabilities allow for the execution of Go source code and the management of symbol tables and type resolution during runtime.
