I, like Steve, disagree.
Coming from c/c++ (and some Java), this was really simple to 
understand:
x"deadbeef"
While this took a lot more time to understand:
hexString!"deadbeef"

For hexString, I had to understand that ! is for function 
template instantiation, and I also had to find out what library 
to import.
