Support for outer i = ...

[pochoi]

I am wondering if a macro for the compatibility of new syntax for outer i = ... would be useful.

for outer i = ... is introduced in Julia 0.7 JuliaLang/julia#22314 in order to distinguish the different behaviours of for i = ... between 0.7 and older versions.

Julia in older versions gives error ERROR: syntax: invalid iteration specification for this new syntax.

I agree this would be nice to have, but the for outer ... fails at the parser level (on 0.6), so a macro never gets to see it. One could conceivably introduce a @for_outer macro so that

@for_outer i = ... begin
    ...
end

does the expected. But I'm not sure it's worth it.

Closing as outdated since we've dropped support for Julia prior to 1.0.
