As it turns out, the joining of adjacent strings is a critical feature.
Consider the following:
f("a" "b");
f("a" ~ "b");
These are /not/ equivalent. In the former cases, 'f' receives a string
literal as argument, which means that the string is guaranteed to be
zero terminated. In the latter case, 'f' receives an expression (which
can be evaluated at compile time) as argument, so the string may not be
zero terminated. This is a critical difference if 'f' is a (wrapper
around a) C function.
You worry too much. With 'f' a wrapper around a C function that takes a
const(char)* argument, if the argument is not a literal string then it
won't compile. Only string literals are implicitly convertible to
const(char)*, not 'string' variables.
