Comparing Objective Caml and Standard ML
The article compares Objective Caml (OCaml) and Standard ML (SML), two prominent languages in the ML programming family. It highlights differences in language design, tool availability, and social factors that may influence a programmer's choice. The comparison aims to illustrate which language may be more practical or mathematically pure in various aspects.

Opening excerpt (first ~120 words) tap to expand
This page compares point-by-point the Objective Caml (OCaml) and Standard ML (SML) programming languages, the two main representatives of the ML programming language family. The comparison includes language design and current tool availability, as well as further social factors. This page isn't meant to be a complete comparison, but rather to highlight differences that might lead to choosing one language over the other. For many of the points below, there is a clear distinction between the languages as to which is more "practical" in that design decision and which is more mathematically pure, concerned with formal properties of the language, or otherwise research-oriented. In such cases, these icons appear: ...next to the more "practical" language ...next to the more "pure" language
Excerpt limited to ~120 words for fair-use compliance. The full article is at Chlipala.
