What does it mean? If you have code that will be compiled at runtime, it works:

require A;
A->import('$var');
eval 'print $var; 1' or warn $@;

> why sub1 imports just fine with require and $var doesn't

Strict checks that variables are declared before you use them. It doesn't check subs when it's sure it's a sub, i.e. when parentheses follow the sub name. Try using sub1 without parentheses: the compiler will only see a bareword, not a sub call, and will complain.

Update: reworded.

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

In case it further helps you appreciate the differences between use and require, see this built-in vs user-defined function coding style advice.	[reply]
