So you'd iterate through the list and accumulate a sublist until you hit a 47, at 
which point you bang your sublist through a [list implode] to yet another 
accumulator (and clear the sublist), and repeat until you hit the end of the original list, 
at which point you bang the final imploded list to the outlet.

Instead of:

[symbol bat/cat/rat(
|
[zexy/s2l /]

Keep in mind that [list implode] must be smart enough to output the float 
atom "12" given the input "49 50".  If it gives you "symbol 12" then your 
back to the [makefilename] madness from my original vanilla solution.
