Hi monks,

I wonder how hard would it be to create a lexical version of the lib pragma. Illustration:

# @INC is (a,b,c) here
{
    use lib::lexical "d", "e";
    # @INC is (d,e,a,b,c) here
    require Foo;
    {
        no lib::lexical "b", "c";
        # @INC is (d,e,a) here
        require Bar;
    }
    # @INC is (d,e,a,b,c) here
}
# @INC is (a,b,c) here

I've read perlpragma and know about %^H, but don't know if it can help in this case. I'm also aware about modules like B::Hooks::EndOfScope, but in this case we want to execute code after the caller's end of scope.

Anyway, there's always this if the above is not possible: 

# @INC is (a,b,c) here
{
    local @INC = ("d", "e", @INC);
    # @INC is (d,e,a,b,c) here
    require Foo;
    {
        local @INC = grep { $_ ne "b" && $_ ne "c" } @INC;
        # @INC is (d,e,a) here
        require Bar;
    }
    # @INC is (d,e,a,b,c) here
}
# @INC is (a,b,c) here
