> Living proof that languages doesn't need forced types.

The opposite surely? TCL is practically dead, and only lingers on in the EDA industry (which has zero taste). Virtually every successful language today has at least a few different basic types for numbers, arrays, strings, maps and so on.

TCL's typicing discipline comes from shell languages and awk, which are decidedly not dead. The overwhelming majority of programmers have less than no taste, so language usage rates in general don't really mean much.

Tcl has these types as well. They are special strings.

Number: string of digits. List: strings separated by space. Dictionary: key value pairs in a list.
