With our process that involves ~50 PRs in flight (and counting, this will only start going down after 16.0 is out), any impediment to automatic merge resolution is a significant...

Trajectory planning before launch (or spacecraft design)

From https://github.com/mockingbirdnest/Principia/issues/4050 and many earlier discussions; it would be nice to be able to do something like the GRAIL launch. - We would want a flight-plan-like entity whose manœuvres are...

Ambiguous pointers

##### Low-priority thoughts on alternatives to the polysemic `T*`. As discussed, C-style pointers `T*` (and C++ references `T&`) have many possible meanings which are not explicit. Moreover, cdecl code forces...

Never use ICU properties

See #1072. CollatorEquivalencesNew and GenerateNormalizeForMatch both have this: ```java static UnicodeSet.XSymbolTable NO_PROPS = new UnicodeSet.XSymbolTable() { @Override public boolean applyPropertyAlias( String propertyName, String propertyValue, UnicodeSet result) { throw new IllegalArgumentException(...

There can only be one XSymbolTable

See https://github.com/unicode-org/unicodetools/issues/1072. In particular, UnicodePropertySymbolTable is eerily similar to UnicodeSetUtilities.MySymbolTable (used in the JSPs). TestUnicodeInvariants.ChainedSymbolTable (used in the invariants) has a lot of the same features (`=@none@`, unary-query for binary...
