I'm producing some examples of the echo function.
I came across a funny scope thing.
> z=0;
> //i=3;
> j=4;
> k=5;
> i=3; // comment out & uncomment line 2
>
> i = echo(j=j,k=k) z; // set new value of i to z (ie 0)
> echo(i=i,j=j);
>
> o= 10 + echo(i=i) 5;
> echo(o=o); // 15
That works as expected.
If you invert the commented out lines it produces
> WARNING: Ignoring unknown variable 'j'.
> WARNING: Ignoring unknown variable 'k'.
> ECHO: j = undef, k = undef
> ECHO: i = 0
> ECHO: i = 0, j = 4
> ECHO: o = 15
I can understand the strange scoping behaviour if j or k was dependent on i,
buy i is the target of the assignment, I can't see why this happens.
Bug?
