In general yes, in this case (mostly) no. Most syntax 
highlighters use the fact that identifiers may not start with a 
digit. They interpret anything starting with a digit as a number 
up until a character that definitely isn’t part of a number like 
an operator or space. Even run.dlang.io does this. 
`03284FHKLLL.dfd.d..f_if` is highlighted as if it were a number.
