How about 1+\dfrac 1{2+\dfrac 1{3+\dfrac 1{4+\dfrac 1 5}}}?

A way to get a "mathematical abstract syntax tree" that can be operated
on and transformed into that or any of your notations
[1+1/(2+1/(3+1/(4+1/5))) might be the default] for numeric objects (and
other things such as matrices and vectors) might be nice.
