Not exactly sure what you want the results to look like, next time, please post that as well. How about something like this:

while (<DATA>) {
    my ($name,$type,$value) = $_ =~ /^blah::(\w+)\s+(\w+):(\d+)/;
 
    print "blah::$name=$value\n" if $name and $value;
}
 
__DATA__
blah::status integer:22
blah::max integer:5
[download]

blah::status=22
blah::max=5

UPDATE: no, it isn't. Just do what Roy Johnson suggested or try:

my %table;

while (<DATA>) {
    my ($name,$type,$value) = $_ =~ /^blah::(\w+)\s+(\w+):(\d+)/;
 
    $table{$name} = $value if $name and $value;
}
