Of course it's not possible.  So we came to what it started with: it is in
principle impossible to have, for example, "for" loop in the standard
library instead of the language proper in a C/Pascal/Ada/Java-like language
even if it were up to us to move it there, because these languages lack the
necessary expressive facilities.  It is possible in Smalltalk, CL, or
Scheme--even Tcl weird as it is.
