I was wondering if there were any real drawbacks associated with using LOGO? I know it's meant for teaching kids, but it could theoretically be used for higher level projects. Are there any real drawbacks beside the many different versions of it?
Apart from the practical issues (cross platform support, libraries), I think the main issue is that it has dynamic scope (see this discussion). That tends to get confusing, particularly for a functional language, and leads to difficult-to-solve bugs.
But, other than that, I understand it’s a pretty cool (lispish and underestimated) language (see link above, which has an interesting discussion).
