The real problem with those is that they don't measure what is, in many cases, the most important benchmark... how fast it is to write solid, maintainable code in the language. Without that benchmark, all the other ones are useless, imo.RA2
Indeed! But if you look at the last section here (code lines): http://shootout.alioth.debian.org/benchmark.php?test=all&lang=tcl&sort=cpu
, you'll see that in many instances, TCL is among the languages where the least number of lines are required to execute a function. We can therefore have a reading on how fast it is to write solid, maintainable code in TCL compared to other languages.
The axiom would be: the shortest the code required, the faster it is to write it. On this aspect TCL has also excellent marks.
