Confusing line number on variable both declared local and global

[anqur]

I was experimenting with local/global scoping in a non-interactive context, and stumbled upon this snippet:

for i = 1:10
    if false
        local a
    end
    global a
end

The line number from the error output is kinda confusing, which is 1. It's expected to be 3 (on local a) or 5 (on global a) I believe. Any ideas?

ERROR: LoadError: syntax: variable "a" declared both local and global

I suspect the reason for this is that the expression where this is "discovered" is the for loop, which begins on line 1, but agree that the message would be clearer if it included info about where the specific conflicting declarations appear.
