pub fn parse_function_call(
    ctx: Context, 
    body_ctx: Option<Context>, 
    params: &ParamsDesc, 
    args: &ArgsDesc, 
    tailstrict: bool
) -> Result<Context>

Creates correct context for function body evaluation, returning error on invalid call

• ctx used for passed argument expressions execution, and for body execution (if body_ctx is not set)
• body_ctx used for default parameter values execution, and for body execution (if set)
• params function parameters definition
• args passed function arguments
• tailstruct if true - function arguments is eager executed, otherwise - lazy
