[New-bugs-announce] [issue22754] Implicit String Literal Concatenation Is Evil

[Aaron Klish]

New submission from Aaron Klish:

Implicit string literal concatenation where
"string1" "string2"
becomes
"string1string2"
should be a language syntax error - not a feature.

This creates a silent error whenever someone builds a list of strings and forgets a comma.

I can't think of any good reason why the language supports this.  There are easier ways to build multi-line strings and there are already two explicit ways to do this on a single line.

It also violates the python principle:
"There should be one— and preferably only one —obvious way to do it"

I realize changing this might break someone's code.  If that is a large concern, maybe the interpreter could support an option to enable/disable support for this.
