Surprisingly, I found there is no documentation for DataType. Considering its importance (the supertype of most types), don’t you think it deserves to have some description?
-------------------------- Julia ver.1.0.2
help?> DataType
search: DataType
Please don’t assume that all the documentation is in docstrings. A lot of it is, but conceptual issues that transcend particular types or methods are easier to document in the manual.
@Tamas_Papp. I read the document and it was helpful. Thanks.
One nice feature of Julia is you can learn the language quickly using RERL so I still think even a brief docstring for DataType can be useful. For instance, I can see UnionAll has the following one so why not for DataType?
UnionAll
A union of types over all values of a type parameter. UnionAll is used
to describe parametric types where the values of some parameters are
not known.
