 A metaprogram is built to generate files before the main program is built. We'll term runtime for this program as `gen_time`. The metaprogram's core implementation are within `gen.hpp` and `gen.cpp` in the project directory.

+There is no parse API for validating excution statements (possibly will add in the future, but very limited in what it can do).
+This reason there isn't one: thats where the can of worms open for parsing validation.
+For most metaprogramming (espcially for c/c++), expression validation is not necessary, it can be done by the compiler for the runtime program.
+Most of the time, the critical complex metaprogramming conundrums are actaully producing the frame of abstractions around the expressions.
+Thus its not very much a priority to add such a level of complexity to the library when there isn't a high reward or need for it.
+
+To further this point, lets say you do have an error with an execution statment. It will either be caught by the c++ compiler when compiling the target program, or at runtime for the program.
+
+* If its not caught by the compiler, the only downside is the error appers on the generated function. Those with knowledge of how that definition was generated know where to find the code that inlined that expression in that file for that definition.
+* If its caught at runtime. The expression will be shown in a stack trace if debug symbols are enabled in the generated function body. Yet again those with knowledge of how that definition was generated know where to find the code that inlined that expression.
+
+In both these cases will get objectively better debug information than you would normally get on most c++ compilers with complex macros or templates.
