I don't understand, I thought you wanted to set a default. Now you are afraid that setting a default will burn you? I am trying to set a hash to a default boolean value unless the hash key exists. Here's an example: That's exactly what my code does. Perl 6 - second systems done right	[reply]

I cannot answer whether you will burn later, but `exists $hash{foo}` will not autovivify `$hash{foo}`. Now, `exists $hash{foo}{bar}` will autovivify `$hash{foo}`, but then, so will `EXPR if $hash{foo}{bar}`.	[reply] [d/l] [select]
