New Methods for Basic data types

Introduction
New methods have been added to the basic data types.
Description
With the objective of coding in a more developer friendly way; new methods have been added to the basic data types (Numeric, Character, Varchar, LongVarchar, Date and Datetime ); so now it's easier to interact with the data types functions. Using the method notation (<attribute>.<method>) instead of the function one (<function>(<attribute>) the GeneXus Developer automatically gets the benefits of the tooltips in the Development Environment.
Syntax
<attribute> = <attribute>.<method>

Considerations
The definition applies to attributes and variables.
Examples
// Old Code using Functions
&var1 = Val(Attribute)
&var2 = Round(Attribute, 0)
&var3 = trim(Attribute)
&var4 = upper(Attribute)
&var5 = Hour(Attribute)
&var6 = Age(Attribute, Attribute2)
&var7 = Ymdhmstot(2002,12,5,10,45,12)
// New Code using Data type methods
&var1 = Attribute.ToNumeric()
&var2 = Attribute.Round(0)
&var3 = Attribute.Trim()
&var4 = Attribute.ToUpper()
&var5 = Attribute.Hour()
&var6 = Attribute.Age(Attribute2)
&var7.Set(2002,12,5,10,45,12)
