This is bad. 99% of the times you don't want a
string/wstring/dstring out of a hex string:

Bye,

this is the API that's about to be proposed, it named as
suggested by A.A., and it handles the two issues you point out:
---
public string hexString(string hexData, bool putWhites = false)()
public string hexString(dstring hexData, bool putWhites = false)()
public string hexString(wstring hexData, bool putWhites = false)()
public ubyte[] hexBytes(string hexData)()
public ubyte[] hexBytes(dstring hexData)()
public ubyte[] hexBytes(wstring hexData)()
---
additionally to x string, a template parameter allows to put raw
whites, e.g
---
assert(hexString!("30 30", true) == "0 1");
assert(hexString!("30 31") == "01"); // standard x string
---
