I was positive that it is intended behaviour that multiple 
imports do not cause an error... It says this at 
http://dlang.org/pretod.html#pragmaonce:

"...D does a symbolic include of import files; they only get 
imported once no matter how many times the import declaration 
appears."

Thus, I'd expect "import std.conv: to; import std.conv: to" to 
compile.
