This is mostly just a list of potential minor issues noticed while coding but not seen worth throwing an error about.

Overall:
	Threading support?

read.d:
	Allow only partially loading a file.
	parseSection():
	as mentioned at end of function
	formatting errors could be more informative; in particular say where the error is

write.d:
	There is currently no way to specify the base in which numbers are written (in text form).

parse.d:
	No support for escaped quotes in strings during tokenisation (by tango.text.Util.quotes).
