You can make your parameters into a struct or tuple and fill them
in with normal assignment. The with(auto) thing will conveniently
limit the scope of the temporary argument object and give a bit
of syntax sugar for it:
with(auto args = ParameterTypeTuple!foo) {
argname = cool;
argname2 = whatever;
foo(args);
}
.....ironically, given the other thread about statements as
expressions where i said 'meh', this is actually a decent case
for them too, to get the return value of foo out of that scope
while still allowing auto.
But that's a separate issue, the main point here is just that you
can use it to prepare the arguments with a bit of sugar.
