End.h	Use this header and `Start.h` in tandem to include third-party library headers which may not tolerate Unreal's common vocabulary macros or its stricter warning policies

Badge.h
Common.h	This header is a central include for all common utilities MCRO offers including higher level features like errors and delegates. You may use the Mcro::Common namespace or use the individual namespaces declared in the individual headers if you notice name conflicts with your own project
CommonCore.h	This header is a central include for simpler utilities MCRO offers. Higher level features like errors and delegates are culminated in `Mcro/Common.h`. You may use the Mcro::Common namespace or use the individual namespaces declared in the individual headers if you notice name conflicts with your own project
Composition.h
Concepts.h	This header exists because STL headers in Android doesn't define STL concepts (other than same_as which is weird), despite the fact that in `<concepts>` the synopsis contains all of them (but only as a comment)
ConstexprXXH3.h
Construct.h
Dll.h
Enums.h
Error.Fwd.h
Error.h
Finally.h
FmtMacros.h	Use leading `FMT_` or trailing `_FMT` fake text literals to create modern formatted strings with a better API
FunctionTraits.h
InitializeOnCopy.h
Macros.h
Modules.h
Observable.Fwd.h
Observable.h
Once.h
Platform.h
Range.h	Bring modern declarative range operations like views and actions to the Unreal C++ arsenal. This header is responsible for bridging compatibility between Unreal containers and range-v3/std::ranges
SharedObjects.h
Slate.h
Subsystems.h
Templates.h
Text.h
TextMacros.h	Use leading `TEXT_` without parenthesis for Unreal compatible text literals
Threading.h
TimespanLiterals.h
Tuples.h
TypeName.h	Convert types to string
Types.h
Void.h	These two are the most useful types in the arsenal of the C++ developer. Use these for dummy types or when it is easier to have explicit return types than dealing with void specializations in templates
Yaml.h
Zero.h
