The rest of your message is spot on and I don't want to dispute it,
but I wanted to point out that while type similarity is misleading,
you should have used integer types in Tcl as well:
vm-hs [~] 25 % tclsh8.5
% string is integer -strict 9999999999
0
% string is wideint -strict 9999999999
1
% string is double -strict 9999999999

The 'integer' check above is a native int type check, whereas wideint
is the native "wide" integer (int64_t) and double is double.
