"makesymbol" is something between "symbol" and "makefilename",
thus storing and creating (formatted) symbols...
TODO:
the use of only "%s" is really not very satisfying
LATER:
split the entire format string into subformats with only
one format-placeholder ("%[^%]*[diufFgGxXoscpn]") .
split the entire format string into subformats with only one format-placeholder,
store the types
when a list comes in, evaluate each subformat (with prior type-conversion)
