pure is always a worry for me, but yeah @safe and ideally
nothrow (if they are forgiving which they absolutely should be,
there is no reason to throw an exception until its time to
inspect it).
I frequently find it useful for a text data file parser to call a
diagnostic callback instead of assuming some default behavior
(whether that's forgiving, printing warnings, throwing or
something else). With template callback parameters the parser can
throw if the user wants it or stay pure nothrow if no action is
required.
