How about a Hash template?

Well, it would almost certainly be bad practice to do so. The comma operator 
can be very useful in some cases (such as for loops) but should generally be 
avoided. Here, it's utterly pointless. However, changing what it did in this 
particular case - as useful as that might be - would make the comma operator 
inconsistent, which could have serious consequences.
