Hi,
I don't know if anyone can confirm this, but there seems to be a strange behaviour with expr. I checked the archives and couldn't see anything obvious, so apologies if this is a repeat.
If used in an abstraction and given a $x variable as a first argument i.e.
expr $1 * $f3 * 10
it works properly - substituting $1 from the abstraction's first argument. However, if the first argument is delimited by parenthesis i.e.
expr ($1 * $f3 * 10)
the console reports a syntax error and an instance of the object is not created.
This is no major problem, but I just thought it should be reported.
