here's the code

```
x = 4
print(x)
```

````

````

that's it.

here's the code

    x = 4
    print(x)

that's it.

problems of markdown syntax

was planinig to write a markdown to html in xah html mode. to do so, one needs to decide on the syntax. i decide now, markdown syntax is not good. same conclusion i had i think decade ago.

worst offender is the GREATER-THAN SIGN for block quote. e.g.

> text
> block
> quote
> syntax

required for each and every line. this btw, came from unix fuck.

Other problems, is duplicate syntax. Example: - and * can be used both for list, or bold/underline. And # the header, can also be done by having ============== under it.

The whole saga of CommonMark, 10 years ago, seems in vain. They didn't fix the issues am concerned above. Instead, they focused on the parsing ambiguity. And they actually tried to be compatible as much as possible. In other words, the whole CommonMark effort, is on nerd backend technicality, not the design of the syntax.
