A DESCRIPTION OF THE PROBLEM :
We generally write code where we match a string/integer against multiple items, which we have to write concat of multiple condition checks as below.
“MyString”.equals(“preString”) || “ MyString”.equals(“postString”)

I propose to have a simpler utility methods
- String.sqlIn(array/list of strings/variable number of args)
- Integer.sqlIn(array/list of integers/variable number of args)
 
With proposed methods, the code above would be as easy as
“MyString”.sqlIn(“preString”, “postString”)

Method name can be something more meaningful. Sqlin word is used here as a reference from sql.
