IANAL, but if the paper also contains a full description of the _algorithm_, seeing code excerpts _per se_ should not preclude one from programming the algorithm without having to worry about this.

That said, it would be great if anyone publishing code excerpts would just include a footnote that they are licensed MIT or public domain, so we would not have to have these discussions.
