Hello.

Can please anybody help me create template format2 like 
std.format.format,
so it can access to format string (change it for example)
then instantiate std.format.format template in 
compile-time-checkable way
format!"%d %s"(arg1, arg2)
so compiler can check format string vs arguments count at least.

i.e. if i would write
format2!"%d %s"(arg1)
i should give comile time error

and next difficulties, i want format2 have extra parameter (say 
"prefix"), not passed to std.format.format

for example, format2 should prepent prefix to format string then 
instantiate std.format.format

any advices
thanks

Since `std.format.format` already does this, just create 
templates that simply pass on their arguments to it and let it 
validate them. "Prefixing" the format pattern is trivially done 
(in a separate template) before deferring to `format`.

If you're not familiar with templates and the difference between 
compile-time and runtime parameters, there are several good 
write-ups, such as the template chapter of Ali Çehreli's book 
(which is available online at 
http://ddili.org/ders/d.en/templates.html).
