Evaluate a Gerbil Scheme expression using gxi and return the result. Use the imports parameter to make module bindings available. Example: expression "(json-object->string (hash ("a" 1)))" with imports [":std/text/json"].

List all exported symbols from a Gerbil module. Example: module_path ":std/text/json" returns read-json, write-json, etc.

Check if Gerbil Scheme code is syntactically valid without evaluating it. Uses the Gerbil expander to verify the code can be expanded.

Show the macro expansion of a Gerbil Scheme expression. Returns the core-expanded form using syntax->datum. Example: "(when #t (displayln "hi"))" expands to a %#if form.

Search for Gerbil/Gambit symbols matching a pattern string. Uses Gambit ##apropos to find symbols across all namespaces. Example: pattern "hash-get" returns hash-get and related symbols.

List available Gerbil standard library modules by scanning the installation. Optionally filter by prefix (e.g. "std/text", "std/net", "gerbil"). Returns module paths like :std/text/json, :std/iter, etc.
