One of the most fundamental DNAs of a programmer is what we may call
'batch-moding' Examples from more specialized to more universal:
- preprocessing string search to get fancy algorithms like KMP
- Use a compiler rather than an interpreter
- Write a program (to do a computation) rather than do the computation
(on pen-paper)
The same principle applies to the wetware in the box atop our shoulders.
So if you take Stefan's
has_type env exp type
vs
Γ ⊢ e : τ
The first is ok and preferable to the second if its to be written once
(or a few times). As it becomes increasingly frequent the demand for
(something like) the second will correspondingly increase.
"Something like" because

Here are TWO points that are separate and deserve orthogonalization
1. Mathematicians do good compression of their subject
2. Mathematics is a cottage industry – one uses gzip, one LZ, one good-old huffman
Many arguments seemingly against the first, are under the hood, arguments
against the second.

Yes... Between
has_type env exp type
vs
Γ ⊢ e : τ
Some will find the second frightening; the first ok
Some will find it exactly the opposite -- "prose" and "prolix" are quite close
How much are these judgments objective? Genetic-structural? Just plain
illiteracy/bad-habits?? Open questions...
[And questions unrelated IMHO to the systems used by a certain Mr. Noah to
design a large boat on which our ancestors were collected]
-------------------
tl;dr Unicode is an ISO standard – something mathematicians have never heard of.
Seems like a good idea to take their knowledge and discard their ignorance
