I guess I'm interpreting "I can call a C++ function from my main application in the script..." too stringently.
If wrapping is permitted, then almost any scripting language fulfills that requirement. If wrapping isn't permitted, than almost none do.

One of the nice things about AngelScript is that wrapping isn't required for many of the platforms that AngelScript runs on. AngelScript will generate the assembly necessary to call a native C++ function without wrappers for an absurd number of platforms. Reading the AngelCode forum threads when Andreas is going through the process of adding native calling support for a new platform supplies much of my knowledge of differently normal C++ ABIs.
