The partial integral symbol is not a letter or digit under any circumstances. It is a mathematical symbol. Identifiers cannot contain mathematical symbols in D or C99 or even C#.
Well, but that argument is kinda bogus. Scientists have "invented" their own notation using whatever symbols (characters) they had access to since forever. It's not like they will stop just because language designers are reactionary. :-)
There are lots of interesting letters from various languages that can be used, so prohibiting access to the proper symbols is kinda pointless. The end result is that people just pick inappropriate characters instead.
