Like half the generic code I've written does that. A direct example
for this is my web.d - it makes automatic wrappers for D functions
that are callable through a cgi interface.
D:
int myFunction(float a, string b) { .... }
User's browser goes to:
myprogram/my-function?a=1.5&b=something
And sees the return value. The way the code works is:
(pseudocode)
foreach(member; thing.allMembers) {
member.arguments args;
foreach(i, arg; member.arguments) {
args[i] = to!(typeof(arg))(cgi.get[arg.name]);
}
cgi.write(to!string(member(args)));
}
Everything in the web interface is string based on transport, so generic
conversions are done to and from all the D types used.
I did something similar with the command line version and with
my D2 dmdscript port.
