Just because the arguments are known 99% of the time at compile 
time, doesn't mean they should be parameters. Parameters 
shouldn't be used to just mean "compile time" anyways, but 
*specifically* to create different versions of a function or 
code, which in this case, is not the case at all.

Besides, there are scenarios where you could pass these as 
runtime parameters from higher functions, if you want the 
exception to "look" like it came from a higher level call. Making 
these parameters would mean that *any* function that handles 
lines or filenames would have to be parameterized on that.
