I think Jilani meant typos, rather than errors due to misused types.

Most dynamically typed or "scripting" languages will catch most instances
of identifier typos before run-time. There are some (not Erlang), that get
it egregiously wrong, though: in Javascript/ECMAScript, for instance, a typo
in a variable name will typically either cause a silently incorrect creation
of a global variable (if on the LHS of an assignment), or result in a
silently incorrect 'undefined' value.
