Hi all, I have a elixir/phoenix project in production written in 1.2.x elixir version. I'm migrating to 1.3.1 and some "unsafe variable" warning appear: most of them were real and useful but I cannot understand the following situation:
#!/usr/bin/env elixir list = [:one] if false do list = [:two | list] end IO.inspect list # warning occurs If, as warning comment suggests, I write #!/usr/bin/env elixir list = [:one] *list =* * if false do* * list = [:two | list]* * end* IO.inspect list # here list is nil list variable assumes an incorrect value. Question is: why elixir compiler assume that block must return a value? Thanks, Nicola -- You received this message because you are subscribed to the Google Groups "elixir-lang-talk" group.
