  This reflects the natural-language distinction between verbal
  phrases and noun phrases. For example, the name »sin« of the
  header »cmath« perfectly reflects what it returns. »sin( 0.0 )« 
  coresponds to the natural-language noun phrase »the sine of zero«. 
  I can not imagine how replacing »sin« it by a verb or
  verbal phrase would improve things.

  The only problem are mixed operations (functions) that both do
  something and return a result.

if( fopen( "alpha", "r" ))...

  Such beasts do not occur in natural-language use. So no
  model for them can be derived from natural-language use.

  A possible solution using an abstract-datatyp object
  would be to separate the two. For example as follows:

File f;
f.open( "alpha", "r" );
if( f.is_ready_for_use() )...
