[erlang-questions] Inconsistent catch behaviour

[Ulf Wiger]

 From the Reference Manual, Ch 6.18:

Note that catch has low precedence and catch subexpressions often needs 
to be enclosed in a block expression or in parenthesis:

3> A = catch 1+2.
** 1: syntax error before: 'catch' **
4> A = (catch 1+2).
3
