How about almost being Javascript? In 1994 I gave a talk and demo at the Second WWW Conference with TCL integrated into Mosaic. It performed the same functions as Javascript later did, and was a very good match also being string based. (ie it was embedded in the page and could control page display and actions.) Even got massive applause from the crowd.
Although it was embedded in our browser (IXI Mosaic) as standard, Netscape was formed at the same time, got huge market share and did their own thing. But TCL could have been a contender ...
I personally switched from TCL to Python in 2000. The lack of a standard way of keeping data and the methods that operate on it together ("object orientation") made larger projects too clumsy.
