For me, "strnum" makes sense, as name for "the concept of a numeric 
string, which is simply a string that looks like a number". This is well 
explained in the manual: 6.3.2.1 String Type versus Numeric Type

Once you are looking at the debugger, here 2 surprising error messages:

$ echo 'BEGIN{a; b[1]}' > test.awk

$ awk -D -f test.awk
gawk> eval "typeof(a)"
awk: cmd. line:1: error: attempt to use non-function `typeof' in 
function call
gawk> eval "isarray(b)"
awk: cmd. line:1: error: function name address@hidden' previously defined

IMO, replacing isarray() with typeof() was a good idea.
