The compiler could limit the call expression to a few lines 
unless the verbose flag is passed.


A similar problem exists when calling a function literal which 
errors, the whole body is printed which can be long.

Ideas to reduce error message size?

[Paolo Invernizzi via Digitalmars-d-learn]

Hello everybody,

If a compilation error is thrown with CTFE involved, the 'called 
from here' is like:


 ```
src/api3.d(2010): Error: uncaught CTFE exception 
`object.Exception("42703: column \"system_timestamp_ms\" does not 
exist. SQL: select coalesce(count(system_timestamp_ms),0) from 
dev_samples where device_id = $1")`

src/api3.d(39):thrown from here
src/api3.d(49):called from here: 
`checkSql(Schema("public",  
src/dget/db.d(276): Error: template instance 
`api3.forgeSqlCheckerForSchema!(Schema("public", **BAZILLIONS of lines**>  error instantiating

 ```

Simple question: there's a pattern to reduce the outputted stuff 
someway? Everything is related to a single struct, `Schema`, used 
during compile time stuff.


Thank you,
Paolo
