copied!<p>To be honest: I don't think it's a good idea as you described, but does have potential.</p> <p>This limits you with an 'annoying' burden of C++'s static number of arguments, which is may or may not what you want in your language.</p> <p>Imagine this - you want to represent a function:</p> <pre><code>VM::allFunctions["functionName"](variable1); </code></pre> <p>But that function takes two arguments! How do we define a dynamic-args function? With "<code>...</code>" - that means <code>stdargs.h</code> and <code>va_list</code>. unfortunately, va_list has disadvantages - you have to supply an extra variable that will somehow be of an information <em>to you</em> of how many variables are there, so we change our fictional function call to:</p> <pre><code>VM::allFunctions["functionName"](1, variable1); VM::allFunctions["functionWithtwoArgs"](2, variable1, variable2); </code></pre> <p>That brings you to a new problem - During runtime, there is <strong>no way to pass multiple arguments</strong>! so we will have to combine those arguments into something that can be defined and used during runtime, let's define it (hypothetically) as </p> <pre><code>typedef std::vector<Variable* > VariableList; </code></pre> <p>And our call is now:</p> <pre><code>VM::allFunctions["functionName"](varList); VM::allFunctions["functionWithtwoArgs"](varList); </code></pre> <p>Now we get into 'scopes' - You cannot 'execute' a function without a scope - especially in embedded scripting languages where you can have <em>several</em> virtual machines (sandboxing, etc...), so we'll have to have a <code>Scope</code> type, and that changes the hypothetical call to:</p> <pre><code>currentVM->allFunctions["functionName_twoArgs"].call(varList, currentVM->currentScope); </code></pre> <p>I could continue on and on, but I think you get the point of my answer - C++ doesn't like dynamic languages, and it would most likely not change to fit it, as it will most likely change the ABI as well.</p> <p>Hopefully this will take you to the right direction.</p>
