Free scripting language similar to Torque's?

Does anyone know of a free scripting language that is similar to Torque's? I'm looking for something that can be *easily* into an application and one which shares its syntax with C/C++. The main features I want are:

- call script function in C/C++ natively (no calling a function to call another function)
- call function in C/C++ application from a script
- call a script function from another script

Any suggestions? I tried out SeeR but you have to use a utility function to call a script function, and it got messy when I tried to call a script function from another script.

Thanks
