@mousetraps just ran into this totally garbage error message

[ts] Cannot invoke an expression whose type lacks a call signature. Type 'String' has no compatible call signatures.

Given

1. A call expression with one argument
2. whose open paren starts on the next line
3. and whose sole argument is an AsExpression/TypeAssertionExpression

we should give a specialized error that ends in:

It is highly likely that you are missing a semicolon.
