[ ... bytecode! ] -> [ ... function! ]
summary: |
<p>Load a buffer containing
<a href="https://github.com/svaarala/duktape/blob/master/doc/bytecode.rst">bytecode</a>,
recreating the original ECMAScript function (with some limitations). You <b>must</b>
ensure that the bytecode has been dumped with a compatible Duktape version and that the
bytecode has not been modified since. <b>Loading bytecode from an untrusted source is
memory unsafe and may lead to exploitable vulnerabilities.</b></p>

example: |
duk_eval_string(ctx, "(function helloWorld() { print('hello world'); })");
duk_dump_function(ctx);
/* stack top now contains a buffer containing helloWorld bytecode */
duk_load_function(ctx); /* [ ... bytecode ] -> [ ... function ] */
duk_call(ctx, 0);
duk_pop(ctx);
