in reply to Re^2: modify @INC
in thread modify @INC

Would it be an option to do something like:

$a="/my/module/path";
eval "use lib '$a'";
eval { use MyModule; }

I recall once using eval & use together to dynamically load specific modules when needed... This was before I knew about AUTOLOAD and SelfLoader and all...

    No, that won't work. The use inside the eval BLOCK is compiled at compile time, but the string in eval EXPR is not. eval "use Foo"; is nothing but an obfuscated way to say require Foo; Foo->import;

    Neither case is a job for eval here. If you want variable paths at compile time, you do the following:

    my $libpath;
BEGIN { $libpath = "/foo/bar"; }
use lib $libpath;

    If you want to load modules with dynamic @INC at runtime, you make use of the aforemention construct: 
    {
    local @INC = ("/foo/bar", @INC);
    require Foo;
    Foo->import;
}

    eval will not help. And $a is a really awful name for a variable (plus $a and $b are reserved for sort). :)
