--------------------------------------------------------------
The attached Avro schema contains 2 enums (enumA and enumB) with an item named
"VALUE_A". Generate a cpp file for this schema:
{{avrogencpp -i DataSchema.avsc -o DataSchema.cpp}}
The generated source file will contain these definitions:
{noformat}
enum EnumA {
VALUE_A,
VALUE_B,
VALUE_C,
};
enum EnumB {
VALUE_A,
VALUE_D,
VALUE_E,
};
{noformat}
Obviously, that code won't compile. It is possible to fix it manually:
# Add a prefix to enum items (ENUMA_VALUE_A and ENUMB_VALUE_A).
# Provide each enum with its own namespace (e.g. enuma::EnumA). Ugly but works.
# Use a strongly typed enums from C++11.
It'd be great to have an option for {{avrogencpp}} to use one of above methods.

Obviously, that code won't compile. It is possible to fix it manually:
# Add a prefix to enum items (ENUMA_VALUE_A and ENUMB_VALUE_A) like the C code
generator does.

# Use a strongly typed enums from C++11.
