> While introducing the new JavaCode abstraction in order to enable tracking references
and allowing transformations, we added 3 types of expression values. They are global variables,
local variables and simple expressions.
> While checking whether we could use this new abstraction for fixing an issue reported
in another JIRA, I just realized that SimpleExprValue contains a string with the generated
code, but this can actually contain other variables. Since the value is carried in SimpleExprValue
is a string, though, we were loosing track of the variable reference.
> So this JIRA is for using a Block in order to represent the java code carried by SimpleExprValue,
so that we don't loose references.
