Subject: Math::String and **

perl -MMath::String -e'print Math::String->new('abc') ** 3,"\n";' Segmentation fault That is a problem of 5.6.1 segfaulting when getting a undef back from overload. Here it means the result of 'abc' ** 3 is NaN, which is stringified undef. Thats more a missiing feature, Math::String should try to convert a second arg to a Math::BigInt, if it fails to produce a Math::String. perl -MMath::String -e'print Math::String->new('abc') ** 'abc',"\n"; ' Can't bless non-reference value at /usr/local/lib/perl5/site_perl/5.6.1/Math/String.pm line 110. Not good. perl -MMath::String -e'print Math::String->new('abc') ** Math::String->new('abc'),"\n";' Can't bless non-reference value at /usr/local/lib/perl5/site_perl/5.6.1/Math/String.pm line 110. Neither. Oh, and I hope I work on it. I wish me luck in fixing this ;)
