TR1 Special Math

[Jonathan Wakely]

Hi Ed,

The C++ committee is considering the
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2015/n4437.pdf
proposal to make C++17 include the contents of ISO 29124:2010 (the
special math functions from TR1 that went into a separate standard,
not into C++11).

What is the status of our TR1 implementation? Is it complete? Good
enough quality to move out of the tr1 sub-dir?

Even if N4437 isn't accepted for C++17 we could move things around to
turn the TR1 code into an iso29124 implementation, do you think that
would make sense?
