[12​:13] <bbkr> rakudo​: my $ = 'a'; my $ = 4; # hmm
[12​:14] <p6eval> rakudo efe72c​: OUTPUT«===SORRY!===â�¤Redeclaration of symbol $
at line 22, near " = 4; # hm"�»
[12​:15] <sorear> my $ = 5 is absolutely legal
[12​:15] <sorear> it creates an anonymous variable
[12​:15] <sorear> it's most useful in parameter lists
[12​:16] <sorear> it prevents unused variable warnings
[12​:27] <bbkr> i know that "my $ = 5" is legal. still "my $ = 'a'; my $ = 4;"
IMO should not warn about redeclaration, because symbol is anonymous :)
[12​:27] <moritz_> rakudo​: my $ = 5; my $ = 7; say "alive"
[12​:28] <p6eval> rakudo efe72c​: OUTPUT«===SORRY!===â�¤Redeclaration of symbol $
at line 22, near " = 7; say "�»
[12​:28] <bbkr> same as ([1,2,3], [1,2,3]) is legal code and those are two
anonymous arrays in the same scope
[12​:28] <moritz_> bbkr​: that's right; it's a bug

From @coke

Same behavior in rakudo 7408d6.
