On compiling. (Was a way off topic subject)

[Chuck Guzis]

There are the languages that are otherwise nearly impossible to compile.

Consider SNOBOL4 (although there is a compiled version called SPITBOL,
but without several hard-to-implement features).  One can construct
statements at run time and execute them. A bit unusual back then, but
not so much today.

In a way, I'm a bit surprised that no version of BASIC (in my
experience) ever implemented this.
