> On the one hand, its approach to structuring data (cram everything into strings, including procedures!) Tcl has not actually "crammed everything into strings" since circa. 1997 with the release of Tcl 8.0. Now, you can obtain a serialized string for most every data structure if you want one, and for quick serializing to a file or debugging this is useful. But the language has not operated solely with strings for everything for a very long time.
