[PD] Inlet Proxy object example

Thanks for this, it looks like a nice, clean example of how to do  
this.  Very valuable.  I'm sure I'll have questions about this stuff.

For example, right now I am in the process of figuring out how to  
parse the object arguments for "?", then dynamically create an inlet  
for each "?" it finds.  I believe the standard is to use "??" as the  
escape mechanism, so that has to be included as well in the parsing,  
but that's not too hard.

I am thinking that one proxy class will be enough, then I just make  
one instance of the proxy class for each "?" found, thereby making an  
anything inlet for each SQL placeholder.  I guess the proxy class  
should include the pointers for making a linked list of proxy classes  
to store all the instances.

I was trying to figure out how this is done in [expr], but that code  
is super strange, so no luck yet.  Anyone else have examples of  
dynamically creating inlets in C based on object arguments?

Using ReBirth is like trying to play an 808 with a long stick.    -
