I think that should be `lock ${$hash{key}};` [download] The idea is that `$scalar` is shared, and therefore lockable.	[reply] [d/l] [select]

That works out well. It's weird that it's mentioned in the POD as something that should work without all of this hoopla. The design behind perl threads _really_ wants to make it hard to share data, it seems.	[reply]

To continue with this theme why not to share a ref to a hash. Like so: `... use threads; use threads::shared; ... my $href : shared; $href = &share({}); ... # Lock block { lock $href; $href->{mykey} = 'myval'; } ...` [download] For more see perldoc threads::shared. - BR	[reply] [d/l]

If the OP wanted to lock the hash, `lock(%hash)` would be sufficient. However, he wants to lock an element of the hash.	[reply] [d/l]
