Do you want to create a variable with the name read with readf? 
If yes, that is not possible. Variable names need to be known at 
compile time.

If you are asking to have code that uses a runtime string as a variable 
name, you will not be able to do that in D. You have to know the name at 
compile time.

However, you can store data mapped to string names using an associative 
array:

int[string] variables;
variables[name] = 0;

// use like
writeln(variables[name])
variables[name] = 5;

This is not possible You would need a scripting language in order 
to do that. What are you trying to do? if your explain better, we 
may try came up with a better solution

This might be possible in certain scripting languages, but not in 
D.

Static fields are generated during compile time, and while 
something like that is possible using template mixins in the code 
(famous use in D is Phobos's bitfields, which generates 
properties for a struct or a class), it's impossible during 
runtime, and - in extension - by reading a value from console.
