> what if I want to only import $var at runtime?

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]

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
