Complex & powerful , Yes.  Thats a double-edged sword, IMHO.
Imagine the entire web as self-selecting.  That would be complex and 
powerful ! (and really really dangerous).

Any language that allows function overloading by signature is "self 
selecting" in the sense you describe templates, IMHO.
e.g. say in C++ or Java

foo( int x );
foo( String x)

... call
foo(  "hi")  ;

Self-selects by the parameter type (and number).   Perhaps not quite the 
same as self-selecting by a select expression but similar in concept.

Some languages self-select by the return type as well (but not java or C++).

Again, powerful, complex, and dangerous.
There have been many debates (undecided  IMHO) as to if this is "good" 
or "bad".
But its unambiguously "powerful".

Not sure exactly what you mean by "fundamental" ... it can have 
different meanings.
