Version 156 is out.

Hi all,

TXR 156 is out. Binaries at Bintray.

Bunch of new functionality and bugfixes. Higlights:

• I/O redirection support in awk macro.
  
• New library for parsing command line options.
  
• Function tracing: trace macro, etc.
  
• Assignment through [obj arg ...] places is now support when obj is a struct
  
• struct type has to support lambda-set method.
  

Cheers ...
