Yup - that's the one.
The LCS parser is very lax, it tends not to flag incorrect syntax if it
can get a reasonable interpretation of what you have written. (i.e. Some
subset of the line - starting from the first char - makes sense as a
We tend not to fix this (usually benign) lax parsing as it can cause
scripts which did compile to stop compiling (as some have discovered).
However in this case the lax parsing of repeat is not benign - you can
write a 'repeat with' statement which looks like it is 100% correct but
does not do what you expect:
i.e. repeat with i = 1 to 10 by 2 -- ignores the 'by' clause
repeat with i = 1 to 10 step 2 -- this is what was meant
Of course ideally the parser would only allow you to use the exact
syntax the engine defines, rather than ignoring 'junk' at the end of a
line... Perhaps something we should do for LC-Next...
