Le forum de XCAS

I noticed x(t) is equal to t: Is this intended? I am including a test of all the single letter functions. I understand i and e, because they are predefined. t(t) makes no sense, so xcas assumes multiplication. I was wondering about x(t).

x and t behaves like that, i.e., x(val) or t(val) will return val. The reason is that many users are using expressions like functions, e.g. f:=x^2+5x then f(2)
and they would be disturbed by the warning message.
Expressions are in terms of x or t most of the time, especially on calculators ports.
