Origins

A debugging class for logging from whence a method is being called. Say you wanted to discover who was calling phase_= in SymbolTable. You could do this:

private lazy val origins = Origins[SymbolTable]("phase_=")
// Commented out original enclosed for contrast
// final def phase_=(p: Phase): Unit = {
final def phase_=(p: Phase): Unit = origins {

And that's it. When the JVM exits it would issue a report something like this:

>> Origins scala.tools.nsc.symtab.SymbolTable.phase_= logged 145585 calls from 51 distinguished sources.

71114   scala.tools.nsc.symtab.Symbols$Symbol.unsafeTypeParams(Symbols.scala:862)
