Hi Andrius,
Yes, I went ahead and checked this into the cvs repository after checking
with the blitz testsuite codes and with a modified version of your example
code. I really should have fixed this long ago. Having binary ops between
TinyVectors and Arrays fail is a major oversight! I will need to produce a
blitz-0.9 (or maybe blitz-0.81 at least) soon to resolve this and other bugs
recently fixed.
