Say I have a template function where there are variations, it
would be nice to be able to specify those variables like
strip!Left(s), strip!Right(s), strip(s), etc...
instead of ahving to do stripLeft, stripRight, and strip.
But the goal isn't just to add an extra ! to type but that it
reduces code duplication.
strip left and strip right are very similar and in a stripping
algorithm most of the code is identical except for the direction
the loop... instead of copying and pasting an appropriately
placed static if could simplify things greatly.
e.g.,
string strip(string dir = {"Left", "Right", default:
"Both"})(string s);
using such a notation could allow us to use such a notation could
make life more interesting... (BTW, I'm not saying this notation
has to be exactly like this...)
The idea is also to avoid littering the symbol table with symbols
so "strings without quotes" are passed. e.g., split!Left instead
of split!"Left" and Left doesn't have to be defined somewhere.
If this notation doesn't work well with template notation then
some alternate could be used
strip@Left or strip#Left..
