 The numbers 1-10, 100 and 1000 will be converted into a 'named' tuple (i.e. "single", "double" etc.). Any other number "n" will be converted to "n-tuple".

+Humanizer can translate time units to their symbols:

+TimeUnit.Day.ToSymbol();
+// d
+TimeUnit.Week.ToSymbol();
+// week
+TimeUnit.Year.ToSymbol();
+// a

 This is just a baseline and you can use this to simplify your day to day job. For example, in Asp.Net MVC we keep chucking `Display` attribute on ViewModel properties so `HtmlHelper` can generate correct labels for us; but, just like enums, in vast majority of cases we just need a space between the words in property name - so why not use `"string".Humanize` for that?!
