I don't see how all this property talk has anything to do with formatting!
:D
Could an option be added to the formatting to elide trailing zero's for %f ?
That way it is possible to create an more optimal formatting for which the
following holds:
float f;
s = format(f);
float f2 = to!(float)(s);
assert(f==f2);
The formatting I'm trying to get can be seen here (decimal):

Looks nice!
Why can't this be in official Phobos1?
It's a ploy from the D2 camp, right?
I've been wanting to write a D-styled data format module but just got
extremely discouraged :)
Most of the functionality I need for this is already available in D2's
std.conv.
Is it possible to add this functionality into D1's std.conv?

The problem I have explaining why somebody should take up D is that I know
not enough about the languages they use to actually show them the things
they are missing. Sometimes it is the, for me, obvious feature like
functions within functions that tilts their heads a bit.
