unhelpful syntax error message when loop variable not a variable

[mlubin]

Put the following snippet in a file, say foo.jl, and run load("foo.jl")

function foo()
    for 1 in 1:10
        bar()
    end
end

The error printed is:

syntax error: invalid assignment lvalue 1 at foo.jl:6
 in include at /mnt/hdd/work/julia/src/boot.jl:201
at foo.jl:0
 in load at util.jl:218

Note that the line referred to is the last line of the function, not the line with the actual error. This could lead to unneeded head-banging.
