Yes, you can do that, but do _not_ do that unless you really
have no other choice. What you need to realize is that because
the file and line number arguments will be unique for every
call to this function, it will generate a new instantiation of
it _every_ time it is called. So, you're going to get a lot of
code bloat. There are rare cases where such bloat would be
acceptable, but in the general case, it's a terrible thing to
do. This particular case might be acceptable given how short it
is, but in general, using __FILE__ or __LINE__ as template
arguments should be avoided like the plague.
yeah I know that but there is really no other way in this case
because of the varargs. Also because of the varargs the function
will be different most of the time when always passing different
arguments. There should be some "give me location of caller"
keyword in D
Also, to nitpick your exact implementation, debug blocks and
assertions aren't even vaguely related. debug blocks are used
with the -debug flag with the intention of being used for
printing out additional debug information (and getting around
restrictions with pure with those messages while you're at it).
They have nothing to do with -release, which is what controls
assertions. What you really want to be doing is to use
version(assert), not debug.
right, makes sense because there is a release with assertion
flags.
