Does SnoopCompile filter out methods that depend on gensymmed names that might not be valid in other versions / builds of julia? In that case, is there any way to keep them,in case you are making your own sysimage for example ? (One of the major contributions to the improved startup in Julia 1.0 was due to changes in the build process that allowed keeping these gensymmed statements)
