i1 : help youngest
o1 = youngest -- the youngest member of a sequence
*********************************************
Description
===========
youngest s -- return the youngest mutable hash table in the sequence s, if any, else
"null".
For the programmer
==================
The object "youngest" is a compiled function.
o1 : DIV
i2 : youngest (bar,foo)
o2 = foo
o2 : Symbol
It should return null, since there are no mutable hash tables present.

Research direction
Reproduce the documented youngest behavior with help youngest and youngest (bar,foo) in Macaulay2, then locate the implementation of the compiled function. Done means a sequence with no mutable hash tables returns null, while the documented behavior for sequences containing one remains intact.
