lor...@gmail.com,

It has been interesting to watch the Rust community put real effort into
improving the error messages generated by the compiler:


Behind the bluster this is all about changing the format of the message.

Format is important because consistent layout reduces confusion.
Also pointing at the actual token that needs to be fixed can be
very hard.  These days compilers hang onto source code position
info so they can try and get this right.

Syntax error recovery was much better back in the 1960s and 1970 because
job turn around time was so long.

When PCs became available compiler error recovery got seriously
worse.
