The deprecation message in 2.066(rc): 'Deprecation: function
std.process.system is deprecated - Please use executeShell instead' is
often not what user wants.
The behavior of the deprecated std.process should most closely be:
int systemNew(in char[] args){
auto pipes = pipeShell(args, cast(Redirect)0);
return wait(pipes.pid);
}
which could be a function in std.process if we deprecate std.process.system
(possibly with a few extra parameters such as environment etc).
Indeed, system doesn't capture output (which could potentially require lots
of memory), and doesn't wait until completion, unlike executeShell.
To make a user's code upgrade from std.process, he most likely will want
something like systemNew instead.
