svn commit: r384782 - in head/devel: . p5-constant-defer

[Sunpoet Po-Chuan Hsieh]

New Revision: 384782
URL: https://svnweb.freebsd.org/changeset/ports/384782

Log:
  - Add p5-constant-defer 6
  
  constant::defer creates a subroutine which on the first call runs given code to
  calculate its value, and on any subsequent calls just returns that value, like a
  constant. The value code is discarded once run, allowing it to be garbage
  collected.
  
  Deferring a calculation is good if it might take a lot of work or produce a big
  result but is only needed sometimes or only well into a program run. If it's
  never needed then the value code never runs.
  
  A deferred constant is generally not inlined or folded (see "Constant Folding"
  in perlop) since it's not a single scalar value. In the current implementation a
  deferred constant becomes a plain constant after the first use, so may inline
  etc in code compiled after that (see "IMPLEMENTATION" below).
