Use D1's writeln, it was a runtime variadic instead of a template.

something like this is what my arsd.core thing does:
https://github.com/adamdruppe/arsd/blob/master/core.d#L11053

it reduces most input to small, factored helper functions to 
minimize generated code. also supports formatting via a wrapper:

	assert(toStringInternal(5.4364.formatArgs(precision: 2)) == 
"5.44");
