+(l) get rid of missingh
+ -> huge dependency and we just need one function of it
+
+(l) get more details what takes time
+ -> use Data.Time.Clock
+ -> seperate analysis, jit, execution, ...
+ -> maybe use ghc profiling? (it doesn't measure native execution, but well)
+
+(h) patching also possible with harpy?
+ -> we can use a own buffer @ codegeneration...
