Why do I have to cast arguments from int to byte?

I keep having to make casts like the following and it's really 
rubbing me the wrong way:

void foo(T)(T bar){...}

byte bar = 9;

foo!byte(bar + 1); //Error: function foo!byte.foo (byte bar) is 
not callable using argument types (int)	
foo!byte(cast(byte)(bar + 1));

It wouldn't be so bad if I didn't have to use the word cast 
before each cast, bust since I have to specify both the word cast 
and the cast type and then wrap both the cast type and the value 
in brackets... it just explodes my code into multiple lines of 
unreadable mess.


void foo(T)(T bar, T bar2, T bar3){...}

byte foobar = 12;

foo!byte(foobar + 1, foobar + 22, foobar + 333);
vs.
foo!byte(cast(byte)(foobar + 1), cast(byte)(foobar + 22), 
cast(byte)(foobar + 333));

Why?
