Reminder that TCL was programmed at a time when SPARCstation IPXes with a maximum of 96MB RAM were being used. Some of the lower-end SPARC machines could only have 16 or 32MB RAM and had perhaps 10 to 12 MIPS of computing power. Expect, which became a very important extension of TCL, was released in 1990, when the SPARCstation 1+ with about 15 MIPS and max RAM of 128MB was introduced. Thus any extension language like TCL had to be small and efficient; especially when you consider it was designed to be embedded inside another program.
