(tye)Re2: [substr] anomaly or mine?

Well, @a[1..3]= "x" is the same as @a[1..3]= ( "x", undef, undef ), and so this seems reasonable to me. [ Note that scalar context changes things since list assignment is documented to return the number of items in the right-hand-side list when evaluated in a scalar context so 1 == scalar( @a[1..3]= "x" ). ]

If there were a way to assign to some kind of variable-length array slice, then we could make a more appropriate comparison between it and the substr "bug" case.

Agreed tye, my bad. If you take a look at my updated version, once I remembered the syntax for slices (not so very hard) it actually made the point I set out to make in the first place. That yo can use a slice as an rvalue in a list context and get the result that you would expect! I spent 2 hours verifying the original bug and chose to post rather than mention it in the CB cos I often get extreme lag as you saw earlier. I end up trying to answer the question before the last question asked etc. Then I had a brainfart ........ What's this about a "crooked mitre"? I'm good at woodwork!	[reply]
