[Gambas-user] Removing / Modifying IsXXXX() functions in Gambas 3

[Benoît Minisini]

Hi,

I'm currently thinking about modifying/removing all IsXXXX() functions in 
Gambas 3.

They mainly test the datatype of their expression. So, either the datatype is 
known at compile time, and there should be no need of testing it ; either you 
are using a Variant, and you can use TypeOf() to get the datatype of the 
value.

I will replace them by some functions that will test if a value can be 
converted safely from a string by using localization. This is what most users 
expected from these functions.

For exemple, in french localization:

	IsDate("13/2/20") -> True
	IsNumber("3,34") -> True
	IsInteger("3,34") -> False
	IsNumber("3.34") -> False
	
Internally, they will use Val() and see if the conversion works.

I will kept most of the name, so there will be a big incompatibility between 
Gambas 2, current Gambas 3, and final Gambas 3.

What do you think about that? 

Who is using the IsXXXX() functions, and in which context?
