--- Comment #2 from Robert Wilhelm  ---
This is a lexer issue.

In lex.c line 432ff, we check the char before the dot (ctx->ptr[-1]).
This is wrong for line continuation.

lex.c:

case '.':
        /*
         * We need to distinguish between '.' used as part of a member
expression and
         * a beginning of a dot expression (a member expression accessing with
statement
         * expression) and a floating point number like ".2" .
         */
        c = ctx->ptr > ctx->code ? ctx->ptr[-1] : '\n';
